fudge .the 400
looks like if you sawwed some in two , and put both in , you could have a pretty good lightweight parallel ( ' V ' ) twin .
A 270 crank being a V in a parallel injun . Moit . about a 750 . tho they could do a liddle 500 I supose .
The old 3TA had 17 inch wheels . Put a 500 barrel on it , and behold . a 500 . So a 750 or 800 would make more sense , innit . Too .
Desert enduro & the like , easyer to stay withit than the current monsters , if your not of a giant . Stature .
