2010 Triumph Sprint

Why’s it in?

As stock the owner’s not happy with the bike’s performance…

Our treatment

The issues with this bike mainly concern power and power delivery off the bottom especially two-up. It’s been back to the dealer and had the latest factory tune, but the owner wants a little more. First job? Isolate the Lambda sensor and cap off the emissions unit. The bike was then put on the Dyno and we reprogrammed the stock ECU; fuelling at the bottom end has been richened up, taking away the ‘hunting’ snatchiness. Fuelling all the way through the rev range has been optimized and the ignition curve trimmed.

The result…

We’ve gained 7bhp at the bottom – which is what the owner wanted – and 4-5bhp at the top, which he wasn’t bothered about so much, but has got anyway! Check the Dyno curves – the stock bike is in blue, the BSD Performance tune red.
