Following on from the success of the RC8 R Track, the 200 examples are to have the same specification as the EJC bikes that will see riders from more than 13 Nations battle across eight rounds as a support race for the World Superbike Championship. Priced under € 10,000 (Rs. 6.75 lakhs) and not homologated for road use, the 690 Duke Track is fitted with a host of KTM PowerParts, bespoke items and modifications to some standard parts to make truly a formidable circuit weapon – losing 10kg over its 150kg road counterpart and gaining 9hp.
The power increase – on what is already the most powerful production single cylinder motor – is achieved from a full titanium Akrapovic exhaust, modifications to the airbox and PowerParts camshaft with a bespoke fuelmap. Ergonomic changes come from a PowerParts seat – firmer, higher and more room for the rider to change position on the bike. PowerParts foot pegs increase ground clearance and move feet back and up while narrower Renthal handlebars took the hands in closer to a race position.
The slim chassis and lightweight subframe remains standard, but with ABS not required for track use, this is replaced with a new four-pad radial Brembo caliper and master cylinder helping to bite down on a thicker front disc. New WP front forks raise the Duke 15mm higher and offer full adjustment and the preload only rear shock from the road bike is replaced by a fully adjustable WP item.
Developed in conjunction with KTM R&D, the European Junior Cup and KTM Street Ambassador, Jeremy McWilliams, the bike in EJC guise is already proving to be a formidable track machine delivering big riding kicks. As a bonus, the 690 Duke Track is also frugal on fuel – drinking only 7 litres per 100km of regular unleaded in testing!
