    Think about tyre .   design source , design , moulding and toolings, minimum quantity..  and test.. Kozaru is now prepared with special profile and pattern with oiginal grpfhic design.仔猿では専用タイヤが起こされました. size 90/70-4 に。

不可能な理由 reason why 1/2 absolute scale is impossible- Impossibility..

Example 1

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 ??


夢は捨てられない we can find out the way to realize ...

HOW do you think if we use a 31cc class engine??

Tyre size 4in with outerdiameter 250mm
