Howdie Doki_doki,
thanks for the info; actually, i have been to the os website but it really doesn't state if it has a full cut crankshaft or the efra cut one.
Cos efra cranshafts are naturally ifmar legal as well.
The japanese osspeed website shows 2 different crankshafts... how strange.
In singapore, its totally unregulated except during invitational races (but then, there is no teching anyways, so this point is moot) so everyone runs pretty much 5 porters, modded to hell, 6-7mm type pipes and so on...
If anyone can just confirm that the os speed TZ comes with a full cut crankshaft, that will be really cool...
Thanks again.
-alexander
