Superstock bikes are the closest things you’ll find to bikes you can buy in a showroom. Teams can change the exhaust system, suspension, fuelling settings and bodywork as well as the usual race stuff like rearsets, bars and quickshifters.
While stock regulations dictate teams have to use the machine’s standard fuel tank, these are then modified so they can hold the extra fuel needed to do two laps of the 37.73mile mountain course. Superstock machines are very close to superbikes in terms of lap speed. Ian Hutchinson holds the class lap record at 133.098mph.
