m max derestrictor box?
as stated above do they work if so how do they work i have been offered 2 the last month! but i also declined because i dont really know what they destrict? do they change the rev limiter? cdi to uk spec? or just simply do the mod that you can do to the speedo ?
any help would be greatly appreciated
thanks david

They remove the 180kph (112mph) factory restriction that all Jap market bikes have.

It'd be cheaper to do the resistor mod, find it in the docs section

and cheaper still to just cut away the disk inside the speedo head - well free actually
