CRF Compression

[MxKid512]

Is anyone else wondering why the compression ratio on the new Honda is only 11.5:1? Aren't Yamahas 12.5:1?Just Curious.:think

Because Honda's are always known to be very reliable, this is one way to make an engine last longer. Honda has always been inovative to find other ways to make power than just big bores and high compression ratios

That's one of the reasons that I predict the YZ 426 or 450 will have more HP than the Honda. That is the single most important thing you know.;)
