Hmmm, interesting... I was trying to import ZX-25R for months when it was announced in eastern markets... Had dealer that was going to take money-down to import one as track-only bike. Then saw specs and it was ho-hum boring...

ZX-25R weights 60-lbs more and only makes 5bhp more than my MC22... And CBR250RR is under-rated due regulations @ time; most make more than that. Heck, Dave Moss's CBR250RR makes 58bhp @ rear-wheels!
Alloy frame... dual disc-brakes... I'm not trading in my CBR250RR for ZX-25R any time soon!!!
