Street Triple gets a Yoshi boost

Yoshimura, the purveyors of fine aftermarket exhausts have put the heads together for these fine looking high-level cans for the Triumph Street Triple. According to the PR; the exhausts offer a considerable gain in performance over the stock items (dyno results below), with a significant weight reduction. The stock exhausts top the scales at 7.2kg and with the top-of-the-range carbon slip-ons, the weight is shaved down to 3.5kg.

Watch: 2011 Speed Triple Dyno run

With the full factory fitted arrow system and map fitted it was time to give the Speed a run on a Dyno to see where the power is at. Over two runs the best results were as follows; Power at the crank : 130bhp & 75 ft.lbs torque Power at the gearbox : 124bhp & 72 ft.lbs torque Power at the wheel : 119bhp & 69 ft.lbs torque The bike has covered 4200 miles and is due its first proper service at 6000 so you would expect to see a reduction in power. Triumph claim on a brand new bike the Speed Triple at best puts out 135bhp and 82 ft.lbs torque at the crank with the cans fitted, effectively mine has lost 5bhp and 7ft.lbs of torque.
