Re: Daihatsu HD Piston, A15 flat top?

SSS Kiwi has the right idea in this thread Bike pistons when found will be lighter stronger and allow much higher revs with less load than most car sourced pistons.

I have used Honda XR500 Pistons in a L series 2.3 litre stroker rally engine and being so light they allowed that engine to rev about a 1000 RPM more than normal L series 2400's as people refer to them as, Most were not actually 2400cc more like 2290cc,Therefore check either Wossner or Wiseco catalogs for diameters but I do not believe they give crown heights in most cases but do give pin sizes so some research could be worthwhile
