Supersport Preparation

Honda CBR600

We are currently achieving over 130bhp at the rear wheel from the World Supersport version of these models. We also offer a slightly less extreme version, developing 122bhp at the rear wheel. Our development of this engine has erased several manufacturer weaknesses, allowing us to provide a reliable racing unit. This has involved reworking of the cam retainers and valve gear, modifications to the clutch, and work on the lubrication system.

Price: 122bhp version is £1600 + parts, 130+BHP version is £2250 + parts.

Suzuki GSXR600

While maintaining the stock reliability in this well-made engine, we have developed it to produce 115bhp in carbureted form, and are now realizing over 125bhp from the new EFI model. We are particularly well placed to achieve good results from this unit through our considerable expertise in EFI and engine management.

Price: £1600 + parts.

Yamaha R6

We have developed a very effective cam profile for this engine and, in conjunction with the necessary headwork and compression changes, can reliably achieve over 125bhp.

Price: £1600 + parts.

Please note that these figures are those achieved on a Dynojet 150 without special airbox charging fans which can easily add 7 - 8 bhp to the above figures.
