Replaced the top end on my 96 cr125r! Fit great perform well but the price is the problem. For 70-80 bucks they'd be perfect!

I put it all together very easily, but it blew up in less than 24 hours of installation!

Ordered my wiseco bottom end kit and everything fell together. Fired up second kick, now first time everytime! I will run it very gently, because that is absolute key in a good engine as some do thrash and wonder why the cranks snapped or flattened bearings!!

Good Quality. Fitment issues.

This kit comes with everything you need but unfortunately came with the wrong size valve seals. Note, the bike I bought this for is a 2004 Honda CRF250x. Anyway, after some time on the phone new valve seals were shipped to me next day from Vance & Hines who actually puts the kit together. The valves and springs are made by Fraction MX so the quality is superb. Anyway, I still recommend this product for the build quality.
