Crunching the numbers

The motor puts out 33.53bhp peaking @ 9,700rpm while peak torque is 27.3Nm (19.18lbft) @ 7,700rpm. These figures are similar to the BMW bikes but the tuning of the Apache’s motor has been done by TVS’s engineers to give it a sporty feel to suit the (sporty) positioning of the RR.

Uniquely TVS runs a Bosch fuel injection system while BMW runs a Magneti Marelli ECU, though to meet the next emission norms BMW too will move to Bosch.

The Apache revs to 10,800rpm and is mated to a six-speed gearbox without a slipper clutch. TVS uses a taller final drive for a higher top speed while the ratios in the gearbox remain the same for all the 310 motorcycles.

Dry weight of the Apache RR is 169.5kg. The trellis frame is a split chassis with the rear subframe bolted on to ensure better accuracy in manufacturing. The wheelbase is 1,365mm and it runs on 17-inch Michelin Pilot Sport rubber, 110/70 at the front and 150/ 60 at the rear. These are off- the- shelf tyres but TVS claim the compound and construction have been tweaked based on feedback from their engineers.

Braking is via a 300mm petal disc at the front and a 240mm rear disc with ABS provided by Continental. The ABS cannot be switched off, though the calibration is such that you can pull stoppies. Handy for the sportsbike hooligan who finds themself on a small superbike.

Kayaba suspension is used on all the 310 bikes but with unique damping for the Apache RR, again considering the sporty positioning. In fact Kayaba engineers worked with TVS Racing’s riders to finetune the suspension – 41mm cartridge-type, goldfinished USD’s at the front with a hydraulic stopper and a mono-shock at the rear.
