FX Nytro Torque Monster Clutch Kits

Low engagement doesn’t mean low power anymore!

These clutch kits are tailored per customer (no cookie cutter set-ups) to take the guess work out of the picture. Designed by SBM to improve the FX at engagement, low, mid, throttle responce, engine braking and top speed. Lets talk about engagement. We are clamping the belt harder @ the primary clutch (the small pulley) to reduce belt slip, gain belt longevity and widen the gear ratio. Have you noticed that loading and unloading the sled is difficult because it wants to spin the track and leap forward or backwards uncontrollably. Even backing up is hard and sometimes probematic. Have you also experienced having to blip the throttle a bunch of times to nagotiate a turn at lower speeds? This is where Schmidt Bros Motorsports comes in.

Our clutch kits were developed for each model specifically. This for stroke engine has over 70 ft lbs of torque @ 3,500 rpm’s, so why would you need to engage @ 3,800 – 4,200 rpm’s. You won’t believe how well you will be able to maneuver at lower speeds with the addition of the lower 2,900 rpm engagement. Now lets talk midrange arm stretch. Basically all models over rev from the factory and this means you are above the peak torque and hp of the engine. A stock sleds tach will generally read 9,100 to 9,400 rpm’s with the throttle pegged at mid speeds which is about 400 to 700 rpm’s above peak hp. If you think your Nytro is fast now, try keeping it in the (CAMSHAFT) all the way to top end. Talk about torque monster. A big plus from this set up will be lower rpm’s, which translates into better fuel milage across the board. People always ask, will this affect my top end and I tell the yes. It will give them additional top speed, usually 5 to 10 mph. I believe this question arises from clutch set ups that negatively affect top speed. Get control of your Nytro, make a night and day difference and harness the awsome torque that puts a smile on your face so that you can put it where it belongs, the snow.

Easily installed at home (No puller needed)

FX-Nytro Comfort Clutch Kit:

The Nytro Comfort Clutch kit is for those who don’t like the higher engagement in the Nytro models. This clutch kit lowers the engagement for smooth take-offs and maneuvering. You will experience less track spin, jumpiness, and aggressive backshift (the “thrown forward” feeling). Don’t be fooled by the word “Comfort”. With this kit you will see improved mileage, increased power to the ground, and a comfortable/controlled use of reverse.

Fx-Nytro Stage I:
This kit includes a primary spring, rollers, and tuning fasteners that are profiled for your stock fly-weights. Custom tuned to your weight, riding style, and modifications.

Fx-Nytro Stage II:
The Stage II kit provides all the benefits of the Stage I while adding extra throttle response and pop at higher speeds. Take your Ntyro to the next level of performance where the stock helix can’t take you.
**The 08-09 MTX was geared too high from the factory for proper higher elevation performance. That’s why an optional higher elevation gearing kit w/ oil is available for $59.99.
