Catalyst Spindle on Yamaha Chassis

[Mitch Desorcy]

I banged up one of my spindles on my Viper so I decided to install a pair of Catalyst spindles. I have a 600 Catalyst so I measured the old spindles to the catalyst spindles and were very close. This is comparing the newer spindles that came out in 2020. Spindles look so much better then the old ones. Handling has not changed.

I was wondering if the Catalyst spindles would fit on the Sidewinder/Viper chassis. I wonder what differences there is between the 2020+ spindles vs the Catalyst? Thanks for sharing.
