Lightweight Sidewinder

[Lunch_Box]

Lightweight trackshaft, brake rotor, chromoly skid arms?

Thought about the brake rotor, rear skid arm is a Baker setup so already chromoly, good idea to redo the front one though. Track shaft I am not sure if its worth it with the torque of the 4 stroke, might cause some headaches.

It’s a pretty impressive weight. I have an impulse nytro that I did some work on and it landed at 648 pounds rtr

Honestly I would not worry about the axle giving you grieve.
It was common practice to rifle drill axles back in the early 2000. I had 2 high powered sleds with rifle drilled axles, one of them was my race hill climber that had more HP then my current SW. 1250 triple PSI Genesis, dynoed at 275hp, N/A, no boost. It wasn't a light sled in today standard but it would pull your arms out of socket. LOL
I did a lot of climbs with it, pretty much every chutes in Revy, grass drags and tarmac drags, never had the axle give an issue.

Even today, I always found the Nytro with some simple modifications was a very well balanced sled that carried its weight extremely well, IMO better then the SW.
