    Top end bearing

    Good OEM substitute. Used one on my last top end without issue.

    Shim Kit

    Glad I bought the kit, better than buying individual shims at the Honda shop. Fair price, quick delivery.

    Was good...

    Fit great and was an easy installation but blew it first time I took it to the track.

    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!
