Aprilia Tuono V4 shock

[kokomoto]

I installed a 2012 Tuono V4 rear shock on my 2020 NC750X. I replaced the OEM spring with an 800 lb Hyperpro 186a0800 spring. It's a 6" spring that went on without much fuss. I also installed an NTA3648 needle thrust bearing with fitted washers to make preload adjustments easier. I have 10mm of preload on it without checking the sag, and it seems to be in the ballpark. After returning from about a 1,600 mile round trip to Florida, I can say that it is definitely an improvement. The rear certainly rides much smoother.

The total cost was under $200.

Shock - $85
Hyperco Spring - $80
Bearing - $11

does the res fit without interference?

Good idea on the needle thrust bearing. Never would have thought about that. Appreciate it.

Nope. It makes very slight contact with the black plastic, but doesn't seem to be worth worrying about. The tricky part was getting a couple of washer on each side of the top mount for proper alignment.

I didn't think of it either. I happened to see them for sale on Traxxion Dynamics' website.

Regardless, I doubt I would have even stumbled across that as a solution; sincerely appreciate the post!
