Quality and Price
From what I can see at the time of install, the fitment and quality in manufacturing are great for that price point!
Time will tell on how it wears. I'll try to update on longevity when I get some hours on them.

Primary Drive Steel kit for Honda crf150rb
This is great deal for a stock dirt bike compared to the OEM version. Its fits great, looks great, and performs pretty well. Did about 20 miles on my dirt bike last week and didn't think twice about it. I also got a Primary Drive set for my Honda TRX450r

Solid Product
Fit our XR80R perfectly. Appears to be a high quality product that should provide hours of reliable riding for my son.

4 stars only because it has zero bling
So if you just want a sprocket and chain to get going down the road then this one is for you. Good quality, just not pretty, but for the price, what do you expect?

I've been using Primary Drive for years, the matched set of chain and sprockets is the best value in the industry.

Chain strectches easily
After 4 rides the chain has stretched to the point it will not ride on the rear sprocket properly in two different spots. Riding on soft, sandy track that should cause stretch that easily. My son does ride very fast or hard since he is just learning to ride. Do not recommend this kit.

does this kit come with master link?
A shopper on May 25, 2017
BEST ANSWER: Yes
is this what the kit I need to change the chain and sprockets on my XR80R?
Ian P on Feb 2, 2018
BEST ANSWER: If you are wanting to stay with your stock sprocket and chain sizes this would be a great kit for your machine. However, if you are wanting to change your gearing ratio and chain size you would need to order these items separately.
I need the sprocket size for the primary drive sprocket and chain kit for a 2007 ktm 65. It says stock gearing, but doesn't give other options?
RICKY K on Feb 16, 2017
BEST ANSWER: These gets come pre-made with your stock sprocket sizes and your stock chain size. Your stock front sprocket size is a 14 tooth, rear sprocket is a 50 tooth, and your stock chain is 420x112. I'm sorry for any inconvenience this caused.
