Specs At A Glance

Good To Know

Q: Does this kit include the bearings? A: Yes, the kit ships with the big-end and small-end bearings needed to assemble the rod onto the crank. Press work and truing are still required during installation.

Q: Can I install this without splitting the cases? A: No, a connecting rod replacement requires splitting the crankcase and pressing the crank apart. A workshop with the right tools is recommended for this job.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
