Hello Max,
We do Streetstocks400 and F400 with North Glos
A SS400 bike :
- requires a V5 and current M.O.T. certificate when the bike is scrutineered.
- the bike must not exceed 98Db (which severely limits the effectiveness of any tuning headwork once the exhaust is bunged up)
- needs to start on the button & the horn must work.
- You must use the original wheels.
- Number plate to be fitted too !
An F400 can :
- have the generator and starter motor removed ( bump start required ) which loses a few KG plus a couple more BHP by not running the generator
- Use light wheels (Dymags etc)
- Use a full race exhaust system ( lots more power than a standard exhaust)
Both Formulas allow you to use different suspension units or rework the standard stuff, you can fit race bodywork and the belly pan must be closed and able to contain the fluid contents of the engine. You can use the standard bodywork actually, just fit a catch tank in the belly pan.
You need a sharks fin ahead of the rear sprocket, and must wire lock the sump bolt, oil filler cap and clamp a jubilee clip to the oil filter and then wire lock the jubilee clip to the bike.
The steering lock must be sufficient to prevent your hands / thumbs being trapped by the bars against the tank, and generally the head bearings, swinging arm bearings, wheel bearings must be serviceable. Bike should be clean, free of leaks and have water in the cooling system, not coolant (slippery).
The bike needs to have two front brakes lines (one for each caliper),best to bin the standard rubber lines anyway as they bulge and limit your braking once the fluid gets hot.
EMRA run a "Roadstocks" class - They say the bike must be road legal, but you can have 105db exhaust system (?) and a V5 & working horn and rear brake light.
BEMSEE allow 0.5mm overbore in their F400 class
Thundersport GB allow 450cc in their Junior Powerbikes.
I hope this helps, PM me if you have any other questions
