The bike was in beautiful condition, so we proceeded with meticulous care.
We checked the condition of the steering stem.
It had been disassembled not long ago, so there was some oil present. The configuration was 26-30.
We used Newtech NC100 grease, which is soft and heat-resistant.
We found some play in the swingarm in the left-right direction.
The rear suspension upper and lower bushings are quite stiff. We removed them, lubricated them, and reassembled them, but the lower one still feels quite tight.
With a twin-shock bushing design, lubrication can provide even better results.
The pivot shaft is 20 mm in diameter. It has developed rust and is mixed with grease.
Although the mileage is still low, disassembling and oiling it a bit earlier will help maintain better condition.
Honda’s design allows swingarm replacement without removing it—that’s nice.
If the chain line groove aligns, various parts could be adapted.
We injected NC100 here as well and reassembled it. We adjusted the shim to eliminate left-right play in the swingarm width, and now both vertical and horizontal movement is smooth.
It’s an incredibly heavy swingarm.
