XS825 Belt on Nytro

[Ohiokm]

Does anyone have any input on the XS 825 belt installed on a 2014 Nytro 120"? Basic trail mods, Hurricane clutch set up, Hurricane airbox mod, PC5 programmer, full Hindle exhaust.

Cheers

You’ll likely have to pull a couple grams out of the flyweights, and maybe even back your secondary spring off 10 degrees, that XS belt is a lot softer than a Yammy 8DN and will drag the RPM down while also not requiring as much squeeze for the clutches to hang onto it without slipping. Dave from Hurricane can likely get you pointed in the right direction.

Timkin lists the xs805 belt for a direct replacement for the nytro.

Nytro used a DN belt. The XS replacement is xs 805. The xs belt on my winder lowered the RPMs about 2-300.
