CRF500s or 525s

Recommended Posts

To those guys who trail ride only and have big bored their 450s, what did you think of the upgrade?

I'm 6-5 and trail ride my 450R only (it already has 35oz FWW/uninstalled wde ratio gears/IMS long range tank/lights etc etc) but am looking to possibly big bore it.

Does the bike lose its famous snap and great feel to the motor with the big bore kits?

Which kit have you tried and did it have any problems?

I read on a few threads that the rods werent up to it - is that correct?

I'd love to hear the pros and cons of the big bore kits.

I have over 60 hours on my athena 500CRF. It has a stage 3 cam and carbon pro pipe. It freakin rocks with no downside, otherthen, at sea level it's too much and tires you out too fast. No cons so far. I'm just not tough enough

Thanks dude

I was in your state last august - up Boulder way. Awesom summer weather up there!!!

I guess you need big horses to pull through that thin air.

How as the athena to install?

Have you done any investigation into the Ice cube 500s?

Did you need to uprate the radiators?
