Bought this for my 2004 CRF250x. I like having the assortment of components for replacements as i do my rebuilds and find bolts near striping (due to having over 10 years of age on bike) on the heads. I would have liked it more if the bolts for the shrouds had the better washers (like the OEM ones i normally got from my local dealer) or even the bolts with washers physically attached to them but overall i like this box of bolts laying around. My sons have a CRF50 and CRF110 so this kit comes in handy there too.

Great Set
I bought this set worried about the quality and quantity. I just got it and "so far" I'm impressed. It's a bigger box than I thought. At least 8x10". It weighs about 5 pounds. It's winter, so I haven't actually used the bolts yet, but I can see it's a nice set and would recommend it to others. Considering what I paid for other bolts (like a sprocket set for $15 alone!) I'd say it's a great value.

every dirt bike owner needs this kit
Spec Bolts are a perfect replacement for OEM bolts you loose in the shop or on the trail. Kit has high quality bolts for just about everything on the CRF

Plenty of good stuff!
Has all of the bolts you may need for a quick replacement. Has all of the bolts for the case on each side, for plastics, chain extender bolts, washers and nuts of different variety, front and back disc brake bolts. Plenty of good stuff!

Great quality fasteners but arrived incomplete
These are high quality fasteners, heat treated and well finished. As a machinist I can tell these things immediately. However once I opened the packaging I realized the plastic box that contains the fasteners was missing a latch. And when I opened the box I noticed some of the fasteners weren’t in the original bags that are in each divider, so my set wasn’t complete. I didn’t return this because the few fasteners I needed for my CRF450 was in the box. But for 50$ I was expecting a complete set. Otherwise I’d give 5 stars.
