Back in the days of drum brakes and air-cooled engines, a lot of our favorite off-road motorcycles came with M8x34 Rear Sprocket Bolts. The problem is, these days its getting hard to find these longer sprocket bolts that were used on these older bikes. That's why Specbolt came out with these all new M8x34 bolts.

 

10.9 Grade gold/yellow zinc plating with medium strength thread-lock already applied. Matched with our tough reusable Fuji type locking flange nuts, you've got a combination that will give you years of service.

 

Designed Primarily for Vintage MX Dirt bikes that need 34mm long sprocket bolts, these can be used to replace most any 28mm to 34mm long M8 rear sprocket bolts.

 

Among others, these are great replacements for many of the Vintage Honda CR, CRF-R, CRF-X, CRF-F, XR-R models.

 

Perfect upgrade for Honda CR models made in the late 70s & up that require longer than todays standard (28-30mm long) sprocket bolt.

 

A few examples are as follows:
