duｃati diana を 50％小さくできるものか?ドカティダイアナに見る1/2スケールへの道 Is it possible to 50% size workable with riding possibility ?
way to sanjose 1/2 diana
One of my favorite bike , Ducati diana 250cc engine has piston which diameter is 74mm and stroke is 57mm
When we make 1/2scale as above below picture this must changed to
37mm and stroke is 28.5mm ,it means 30.6cc.
waoh ,it is so difficult world to scale ..
* tyre 2.75-18 must goes to 1.4-9 , should we make it and invest for moulds ??
HOW do you think if we use a 31cc class engine??
Tyre size 4in with outerdiameter 250mm
We will start to definit to call this scaling as kozaru way!!??
Dream size is 1/2 ,
do you feel the possiblity?? we still do not give up it.
put original CK 2.75-9(8?)tyre
if we have a enough budjet (millions or more) , 31to35cc engine by original and 1.5*9 tyre and wheel and many 50 scale components
