Hi all, wanted to know the following dimensions, sprocket shaft end to the other side of any bike engine you might have. I am looking for the shortest (width I can find for my mid engine car. would sp1s and milles have narrower engine being 2 pistons? Any help would be great. and I wonder what is the shortest diff that can be used? Thinkinf of bolting straight onto diff.

why don't you look at one of the big vtwins ? like the honda fire storm or the tl 1000 from suzuki you won't get much narrower and they will give you nice grunty power
best wishes

you could look @ a honda VFR 800

whit sequential injection starting @ the year of 1998 (101Hp) the rest has 110Hp..

its a special engine a V4 whit DOHC etc..

it will measure from sprocket to back some 420mm i guess will measure as soon as i can today..

greetz,

i have it complete for sale also..

twins, as you say, are narrower than most...

I've just measured 2 engines...

a ducati 748 is about 320mm wide

a vtr1000 firestorm is about 370mm wide

if you went for a firestorm you would need to get a really low diff ratio as the VTR engine has a relatively low rev limit, hence your top speed would be a lot lower

the TL1000 or Aprilia would be a better choice. I'm sure there will be others - it's too early for me to think of them though...



the shortest diff I have heard of is a 3.14...( freelander? )
