Connecting Rod Set
As with their gearbox, OSSA did not sell any crankshaft parts separately. For reference, the complete OSSA crankshaft (P/N 3000020211) had an MSRP of $725 USD back in 2013.
Fortunately, the GasGas connecting rod set (rod, pin, big end and small end bearings) is a prefect replacement. It is part number MT280212100 and had an MSRP of $266 USD in 2024.
GasGas also offers the big end bearing alone as part number MT32050GG-AIZ-1. It has an MSRP of $35 USD.

XiU-rdi sells a replacement GasGas bearing, part number 91008-xgf-0004-2. This is a special 6205 bearing measuring 25 x 52 x 15 and incorporating a 30 x 47 x 6 seal. Both sides are identical, and two bearings are required. The price is about $52 each as of 2024.
However, in order to use this bearing for the OSSA, you must accurately grind a slot on the outer sleeve for the locating pin.
