    Love it!

    Been running the same Primary Drive chain & sprocket kit since 2013 on my 2001 WR250F. I haven't noticed much wear, despite me putting on 1,000+ miles on it with little chain maintenance. Would buy again in a heartbeat, but I don't think I will need another sprocket or chain for quite some time.

    Great chains, good sprockets

    You won't find a better deal elsewhere. These chains are superb and the sprockets work well too.

  • Primary Drive Alloy Kit & O-Ring Chain

    Primary Drive Alloy Kit & O-Ring Chain

    RANDY in SC

    Good product

    Purchased o-ring kit to replace a badly worn stock set. Everything fit well with easy installation. Even sent the spacer for the countershaft, a must have when installing a wider chain like an o-ring. Original front sprocket wasn't too bad of shape, but why not spend a couple more bucks & replace it all.

    Great Price. Great Value

    This is the second time I have ordered this chain. I looked at my past purchase and the chain lasted exactly 1 year. I ride 15k+ a year and I am horrible about chain maintenance. Aside from adjusting the tension and when the chain got really dirty I would hose it off and hit it with some 30W oil I did nothing to it. For under $100 that's a great deal to me. Rear sprocket started to hook about 200 miles ago and that was after some hard abusive wheelies. Front sprocket has life left in it and the chain has all the rollers still but is showing signs of stretching.
