2010 - Suzuki RM-Z450 with Timbersled SX Snowbike kit
Timbersled SX kit installed on EFI bike-- ready for the pow!
We just installed a brand new Timbersled SX Snowbike kit on this Zuk! Free spare gas can, too!
Timbersled info: The SX (Snow Cross) kit is a purpose built kit for snow cross racing and rough terrain riding. Although it is the most expensive kit we offer ($1000 more than our ST model), it features an extra shock for adjustability and incredible suspension performance for jumps. It boasts 20" of suspension travel!
The kit uses a hard compound 121” long Snow Hawk track that is 10.5” wide (2” narrower than our ST and LT kits) with 2-1/4” tall paddles in the center of the track and contoured down to 1" on the outer edge paddles (meaning the track is rounded like a tire). This works extremely well on firmer snow condition such as trail and track, yet more experienced riders will prefer it in the deep stuff too, as it corners like a dirtbike with wheels.
Along with the narrower and stiffer track, the sub frame and tunnel is also narrower for a more slim fit on the bike (the tunnel on the SX is about the same width as the bike frame). The drive axle on the SX is 1.5” higher and 1” farther forward in the tunnel than our ST and LT kits. We were able to do this on the SX kit because of the added space we gained for your feet from it being 2” narrower. The SX kit is dual suspended; it includes the same track suspension as the ST and LT models along with an additional shock in the Sub Frame/Swing Arm. This adds up to a total of 20” of rear suspension travel.
Here is how it works: The secondary suspension pivots from the stock swing arm location. It is operated from a strut rod that replaces the stock motorcycle shock and attaches to a linkage arm that pivots to activate the shock mounted horizontally on the snow bike sub frame at a 4 to 1 ratio. This linkage suspension is fine tuned to work in conjunction with the rear skid suspension. All this adds up to a precision feeling suspension that is very tunable for racing and abusive rough terrain.
Previous owner (rode the bike with the wheels): The former owner was out with injuries most of the time he had this bike. He installed an hour meter when he bought it new. It reads 27 hours is all! The suspension has been fully revalved with different springs front and rear (originals included also), Pro-Taper handlebars, ball-bearing throttle tube, and an oversized radiator. The seat bump in the pictures has been removed.
