We can supply all types of TTI gearboxes. They are made in New Zealand by one of our customers, Bruce Verdons` specialist company. They have proven to be at the forefront of reliability.
We stock the latest LW55 6 speed magnesium gearboxes, which we use in our own race bikes. We consider them the optimum for up to around 75 BHP, 50 FT LB. Beyond that you should consider the HD variants. 4 and 5 speed versions are available.
When ordering it is most important that you specify change direction. You can either have `N` where, with a simple gear pedal facing forwards, 1st gear is up; or `R` where 1st gear is down.
There is a choice of mainshaft length:
Manx: 22mm of clutch spline plus 15mm of thread
Commando: 25mm of clutch spline plus 15mm thread
