Bajaj Discover DTS-Si 100 Review
Print This Post
A few years ago Rajiv Bajaj stunned everybody by declaring the exit from the most selling 100 cc segment, a segment that makes Hero Honda what it is currently and for the past many many years and concentrate on the higher segment. This had an immediate effect on the market dynamics where Bajaj lost out badly with sales dropping to as low as a meager 65000 bikes in December 2008 and Hero Honda taking complete advantage with sales sprawling to newer heights.

Understanding the fact that the Indian market is still not ready for upgrading to bigger segment, Bajaj recently launched a brand new 100 cc bike christening it on the premium Discover brand. We have got a lot of queries pertaining to this bike and here we are presenting before you a complete review of the bike. Read on to know how this bike performs to the claims of the company and does this bike packs in enough to give the even-stronger-now Hero Honda any bother!
ENGINE AND TRANSMISSION: Discover brand has seen it all, from a 112 cc engine to a 125 cc one, upgraded to 135 and now this latest 100 cc offering from Bajaj. Bajaj is promoting this bike as a sporty touring commuter and for that the bike needs to be good on more than many aspects. The bike is powered by a single cylinder, 4 stroke air cooled DTS-Si (Digital Twin Spark Swirl Induction) engine which has a displacement of 94.38 cc. Maximum power produced by the bike is 7.7 PS at an early 7500 rpm with the peak torque output of 7.85 Nm booming at 5000 rpm.

Bajaj has developed an advanced version of their famed DTSi technology and calls it version 2.0 wherin a turbulence is created in the air fuel mixture which ensures efficient combustion of fuel for optimum mileage and power. The pent roof combustion chamber has been specially designed which further helps in burning the fuel to the maximum while the Malycote Piston (reminiscent to the recently launched Pulsar 220 DTSi) has also been deployed to this bike which ensures lower friction between the cylinder walls and piston which in turn means better efficiency and longer life of the engine.
XCD 135 was the bike previously which we felt was by far the smoothest from Bajaj and this bike just takes the game ahead which clearly indicates the technical prowess Bajaj is heading to! The engine really feels butter smooth and unstressed returning positive feedback at all the regular city driving rpms. While the bike does run out of steam on long ways but that is understandable for the engine size it is, but let us make it very clear that this would probably be the best bike for commuting on highways if at all you plan to do on a 100cc! The bike also comes loaded with a programmed 8 bit microprocessor which takes care of the spark delivery.
The bike sports an all down gearing pattern and is the only 100cc bike currently in the market which sports 5 gears. Previously LML Adreno had 5 gears and we always loved it for this very fact. The gearing feel is pretty decent but not thoroughly outstanding. One thing we would like to convey to Bajaj is to make the Pulsar 220 DTSi’s clutch standard across all of its models, we simply love it. Not that we did not like Discover’s clutch but definitely has room for improvement.
CHASSIS DIMENSIONS and Styling: The engine is mounted on a Single Down tube frame which feels robust and sturdy and is fantastically designed. The bike sports telescopic shock ups up front with a maximum travel of 130 mm whereas the famed Nitrox Gas shock absorbers make way on this 100 cc at the rear which can travel a maximum of 110 mm and definitely are the best in this segment by far. The bike approaches the potholes with aplomb and carries the bike around corners with sheer ease and pleasure.

With an overall dimensions of 2040 * 760 * 1087 (Length * Width * Height) in mm and a wheelbase of 1305 mm this bike surely is a category above the rest and is bigger than the lot. It provides the user with a big bike advantage and the feel which is grossly missing in today’s 100ccs.
The bike comes loaded with some fantastic styling features such as an all black theme, alloy wheels and a typical Discover headlamp with twin pilot lamps. In an attempt to curb cannibalization from other Discover, Bajaj has kept only black color as the base with three different decals to offer variants on this bike. Three variants are Black with Blue, Red and Green decals. Paint and plastic quality has been Bajaj’s forte and there doesn’t seem to be any cost cutting on this front. Fit and finish is also pretty good considering its price.
PERFORMANCE, MILEAGE & BRAKING: This is where this bike surprises us with its sheer capabilities. The engine, though seems to be low on power on paper, performs faster than our older perceived notions. Zero to sixty KMPH on the speedo is achieved at a tad above 8 seconds and this is at least half a second faster to any other 100cc bike in production currently. These figures are almost at par with the Yamaha Libero G5 which we adore for being the quickest 100cc. That’s not all, the way this bike attains it is way better than most of the same segment bikes in the market. We managed to hit a top speed of 94 kmph on the speedo and for a bike of this capacity, these are pretty decent numbers.

The new age engine definitely is a lot more frugal and the bike returned an awesome mileage of 83 kmpl on a mix type of riding. On roads, for general people this bike must return anything in excess of 75kmpl and these figures are, by any standards, fantastic. A bike running the maximum on one liter of petrol is what India dreams about and here is the bike just for them which performs fantastically well and is probably the most fuel efficient machine in India. With a tank capacity of eight liters, the bike is capable of running close to 600 kilometers before asking you for more fuel with the reserve informing you more than 2 liters in advance.
Braking of the bike is also very good considering that both the tyres come equipped with Drum Brake setup (130 mm front and 110 mm rear), though we would have liked to have a Disc brake as an option at least. Stability is also aided by fatter 3.0 section tyres at the rear. Ground clearance of the bike is also decent enough to keep out speed breakers kissing your bikes bottom and helps in a plusher ride.

TIDBITS: The electrical setup is all DC which is a very first in the segment which ensures a constant supply of power to the horn and headlight at all rpms. The bike also has a 5 Ah Maintenance free battery for lesser hassles and that smooth one click self start and other operations. The tail lamp is beautifully crafted with LEDs which look fantastic, in turn saving power as well. Bajaj’s patented Exhasutec also find a way onto this bike from bigger siblings which increases the low end torque to a good degree which in turn enhances the city drivability experience. This bike also comes with the innovative Auto Choke from Bajaj which ensures automatic 100 percent choke operation on all cold morning starts and whenever the engine needs it, hence no pulling of the choke lever and a smooth first crank start in all weather conditions. This bike also comes equipped with a low battery/ battery malfunction indicator on the console to remind/ inform you of any issue. This bike also sees the introduction of the Ride Control Switch which enhances the riding experience of the rider.
VERDICT: Bajaj has come out with an out and out winner and the sale figures scream at the top of their voice wherin the bike has sold 50,000 units in just 50 days since its launch. With a kerb weight of only 115 Kg, this bike also ensures that it is not heavy for its looks. With an on road price of 44,000, Bajaj continues to play the pricing game with perfection and at such a tempting price tag and a whole bunch of goodies in offer along with a superb engine; this bike should sell like Hero Hondas!

Definitely Bajaj is getting better and better with time and experience so far bike technology is concerned. Bajaj has established its ground for motorcycle manufacturing primarily on Kawasaki’s platform, unfortunately Bajaj has inherited one problematic segment from Kawasaki where Kawasaki itself was always criticized for its bikes- Transmission & Drive chain problem. I hope Bajaj should overcome this drawback of its forever and for every bike of it.

I would advise him to get the Hero Honda Splendor Quantom Core…… blah blah blah, LOL.
vipin_s on October 2, 2009 at 4:15 pm
the new Discover looks value for money in every respect. the looks are also much more premium and prestigious than the splendors or super splendors
vivek chauhan on October 5, 2009 at 9:46 pm
seems to be a good value for money……….
but can attract more customers if it is also available in a less price( 1 to 2 k) without self start.
kara on October 9, 2009 at 12:36 pm
Though with electric start, the price is quite hitching to go for it, coz with a 3K more you can have a 135 XCD, with disk brake, digital meter, and all other features remain same of 100CC discover. XCD is priced at 52 on road, after a discount.
Can anyone tell me why am I not able to see XCD 135′s on road, they are very rare on road, can any one comment on this?
sathish07 on October 28, 2009 at 7:34 pm
here lot of xcd 135 on road in chennai
me too have a dis 135 digi speedo
vishu on November 27, 2009 at 4:11 pm
i like this bike very much as for the features mainly on the millage but the only features i wont like is not come with disk brake……
SankarTL on February 14, 2010 at 8:50 am
Pls clr me what for Ride Control Switch is used & when 2 use. It enhances the riding experience or the milege or both?
Thank you
Anand on February 19, 2010 at 7:29 pm
Hi all,
XCD 135 has good spare parts, but not a gud engine. It has the BORED-OUT version of the old 125cc. which means the crankshaft & gear ratios are’nt altered much. secondly the looks of the bike aren’t great enough to compete with SHINE/ DISCOVER 135/ GLADIATOR. top speed is only 98kmph.
NOTE: CHASSIS IS NOT COMPLETE (engine hangs from below the fuel tank)IN XCD & BAJAJ ENGINES AREN”T AS REFINED AS A HONDA/ YAMAHA. SO VIBRATIONS ARE VERY HARSH AFTER SPEEDS OF 60kmph& ABOVE.
these are the main reasons why people trust HERO HONDA more than BAjaj or any other bike maker.

Hello,
I bought Discover DTSi 100 cc for Rs.46000 in Erode (TN), completed first free service and reached >1200 kms. I am riding at the speed between 50- 55 kmph with good road conditions. But mileage is only between 65-70 kmpl. I am not happy with mileage ….
Thanks
Karthik on February 23, 2010 at 7:36 pm
Young guys please dont buy Discover DTSi 100 cc … its less than half of pickup/speed when compaired to any other bike in same kind. I am using this bike for past 7 month in Metro city it give milage of 70 Kmpl at speed between 40 to 50 Kmhr. As all bajaj bike this one also have noise in its gear system.
I am just satisfied with milage and look
Discover DTSi 100 cc is good for family person (slow and steady).
pandurang kokare on March 3, 2010 at 10:43 pm
i like design of disc 100cc.but i comfused long life and resail value of this bike.milege is good but all baJAJS BIKE COME TO WORK QUICKLY I LISTEN IT.I COMFUSED WITH P PRO AND DISCOVER.
sara on March 5, 2010 at 2:58 pm
I am not convienced with the bajaj dts-si as i am getting mileage of less than 60knpl and lot of chain sound while riding i had my second service done at shakti motors,Chennai i am not satisfied with the service at shakti motors. just for name sake they do service.
Tushal on March 11, 2010 at 11:57 am
Products make or break due to after sales service. Bajaj has quite bad one at that.
kamesh on March 15, 2010 at 11:56 am
hi friends … i have bought bajaj discover 100cc dtsi one month before, while im buying dealer said it would give millage around 75-80 in long and in city 70-75km ,but it gives for me only 60- 65km for 0ne liter in city, other than i have no problem with this bike..while buying this bike don’t have the mentality it ll give around 75-80 km/liter.. top speed up to 90-100. as tire is too thin when compare to other bikes while riding in hard surface and sand we should sloe down the speed to 40 then it would be nice otherwise there is chance to skid. for me it provides millage max to 65 km but im not sure with others . features are really good on road it ll cost 48000 in chennai. power start speed pick up is one of the major advantage of this bike.. for the profession bike rider will get millage max up to 70 km/liter other than we cant expect still more..
palanisamy on March 15, 2010 at 9:54 pm
hi friends ….Last 18th feb, I have bought a discover 100cc. I purchased it from Rajarajan motors at cuddalore in Tamilnadu. When the bike was delivered I did not notice a punch with heavy scratch on leftside telescopic tube. four hours later,I informed the dealer.After 15 days When I went to the showroom for the first service the dealer changed and replaced a new one.Milage of the bike is also good and in between 85-92km/lit but I am not satisfied with engine’s and transmission’s noise.Final word is The dealer is better than my bike.
raghav on March 18, 2010 at 5:45 pm
hi friends just now i booked discover 100cc is it worth or shall i go for pulsar 150cc pl sujust me .
Tushal on March 19, 2010 at 8:11 pm
I still dont know why the discover 135 has 4 speed gearbox. The high revving engine would do good if it has a 1d+4u gear box.
nitin on March 20, 2010 at 10:42 am
dear all, i am really happy with the bike of 100 CC Discover but i am not happy with the type, it too thin and where u ride on joint rode your chances are there that it get sleeped,
i faced the same problem, hope bajaj can come with the MRF type instead of Dunlop, beocz Dunlop typres are worst which give too much problem specially in rainy season
Shrikant Shet on April 20, 2010 at 12:47 pm

mihir on May 16, 2010 at 5:57 pm
hi i am very confused that should i go for bajaj discover bike 100cc or honda stunner.Bajaj 135 is not available. when i saw discover 100cc tyres, i just wanna know that since tyres are very thin will it be risky driving on highway in mumbai , so should i not worry or should i than go for stunner . please guide me regarding this since i will have to travel daily 40 kms(to and fro) on highway so safety is first priority for me
manoj yadav on May 19, 2010 at 1:30 pm
Hi Mihir, you dont get confused If you want to buy economic & value 4 money bike then i will advice you go 4 discover. but if yuo want trsted & smooth bike then defenatly go 4 stunner or newly lonched HONDA CB TWISTER. CB TWISTER is combination of power, style, millage, & safty also,I thing it is best in this segment.
karthik.k.k. on May 29, 2010 at 10:53 am
hi all i got my new bajaj discover 100 cc magna black which really good in style ,i am getting the mileage for 75-80Kms and very confident handling in reiding but if you drive above the 80Kms engine sound is changing it is going up to still 90Kms ,if you go in doubles engine is smooth still 75Kms if you compare to splender or passion it is very good bike i love this bike very much to drive ………………….
Sujay kumar kolebira on June 6, 2010 at 4:51 pm
Hi guy discover 100 cc is too short for tripple ride.we can not stunt from bajaj bike like yamaha.it is good for milage not for resale value.
satish on June 17, 2010 at 12:36 pm
hi all i have purchase discover 100cc it is good and great for one person not for two b’se of not much engine and capacity and about mileage i counted till now 32 kmpl i ride 550 km may not fully running condition one drawback is break in top gear then down the grear, just u have to down acc. to speed .. other wise good looking and greate pickup..
Ranjit on July 10, 2010 at 4:56 pm
Bajaj Discover DTS Si (100cc) sucks… it gives hardly 52 kmpl…
Faced lot of problems, bike is fully shaking while driving after using it for 5 months….
Kallyani Bajaj, Bangalore…Each time I gave it for servicing… instead of fixing the trouble they got it more worse.. Now my indicators sound also not working.this happened 3rd time after servicing..It needs a hell of maintenance.
I have decided never to use Bajaj in my whole life..and would not suggest it to anyone.. Better use Hero Honda or Honda.
chander on July 21, 2010 at 5:29 pm
i got my bike in oct 2009 grt bike very low maintaince milage upto 85kmpl……… good pick up i thik bajaj has done great job,,,,,,,,,,,,,,,,,,,,,,ya bit problem when it reaches to 80-90 its sound changes otherwise great bike
Alokesh on August 26, 2010 at 8:36 pm
I bought this bike on september_2009..so,i hav been riding it since 11 months..it is nice bike .it gives 70-75 km/ltr after 3 servicing..dont expect more than 65 km/ltr before that.very smooth on road..i have hitted a topspeed of 95 km/h..riding it 200 km constantly by giving only 1 tm rest with 1 pillion..it has been reached destination without any problem..atlast i can say it is value for money byk..so,,Go..buy..n discover it..
Amit Kumar Gupta on August 29, 2010 at 9:34 pm
This bike discover 100cc DTS si is worst bike, i have a very bad experience for this bike, this is not satisfactory in any class, like milage, chain system, fitness of the bike.
I have just completed 11000kml, but the chain set sounds like a tractor, there is also problem in battery provided from company.
So, I want to suggest everybody that the idea of purchasing this bike is not good and it will create a distubance in your life.
Abhilash on August 31, 2010 at 10:53 am
it is wonderful bike with great look n riding. i have bought recently
