New FZ FI v2 vs Carb FZ: Most Comprehensive Comparo With List of All Changes

Yamaha was a darling to bring bikes like the R15 in India, giving the performance starved Indians a way to enjoy track biking without spending a bomb.


On the other hand, the FZ was meant to be a city scorcher in the premium 150cc segment. It sure did attract a large and loyal fan following but its growing age was bringing it constant criticism. Adding to the misery were the frequent sticker upgrades which had become a complaint-point for bikers.

Thankfully, after many speculations and a final showdown at the Auto Expo in February, Yamaha has launched the updated FZ-S and FZ Version 2.0 in the market (Launch Article).

A lot of our readers have asked us about the differences in the old and new FZ and in this article we list all of them for your ease of understanding. First up is the spec comparo.

List of All Differences in FZ carb and FZ FI:

Design Changes:

  • The new FZ FI looks sharper and sportier than the older FZ which is a more rounded motorcycle with more curves. On the face of it, new FZ FI looks more agile as well.
  • The headlamps look sharper than the older one, and the rear view mirrors are also larger and more functional
  • The redesigned tank has a larger feel and better knee recesses. It even allows you to hold the bike better. The tiny fairing extensions below the tank also sport a new shape.
  • The split grab rail seems to be much more useable and gets thinner.
  • The redesigned tail lamps looks boring and would have been better had they incorporated LEDs and the transparent panel in the lower part of the tail light would not been missed.
  • The exhaust canister gets shorter and racier.
  • The rear wheel hugger, though not a looker, will be a blessing in the rains.
