Here at Mototrax we didn't take existing snowmobile technology and make it work for a dirt bike. The MTX 120, MTX 129 & MTX 137 Factory Edition models take performance one step further with the IDS (Intelligent Damping System), taking snow bike performance to new levels. Our whole lineup received brand new rear A-arm technology
We added grease zerks on all pivot points to keep your system functioning at optimum levels without doing full tear-downs on the skid, keeping you on the mountain and out of the garage. For the 2022 model year we increased the durability of our system by adding more rail support without compromising weight and improved stress point strength on the bulkhead. Add in 12.5 degrees of lateral articulation and you have the most responsive and nimble snow bike on the mountain. Our track system is equipped with a single shock, rising-rate suspension, just like your dirt bike. Tack the threaded joints at the T's to prevent their twisting.Engineered to your bike's natural feel, the Mototrax snow bike conversion system is the most advanced kit on earth. Tack weld all joints to hold the assembly rigid, then remove the frame from the jig to complete the welding. For clean welds, remove the paint from all weld points. Shape the crossties as shown for a close fit inside the side rails. 5 & 6.įasten the front and reat forks to the blocks on the jib, and you are now ready for welding. As the legs pivot on the fork, they compress the spring, giving the front wheel a sof, cushiony suspension. 909 MINIBIKE KITS 909 MINIBIKE KITS NITRO-50 FRAME AND FORK ONLY 390.00 320.00 EL LOBO 6' MINIBIKE 550.00 455.00 Nitro Ninja Mini Drag Bike Frame and Fork Only 999.00 EL LOBO 10 ' MINIBIKE 650.00 EL TIGER 5' MINIBIKE KIT 425.75 358.95 EL TIGER 6' MINIBIKE KIT 475.00 435. The upper ends of the legs, which now extend above the fork, are anchored to a spring that bears against a plate on the steering column. Bolt the legs to this stub fork as shown, with the spreader bar inserted between them. The spring-action front wheel is made by cutting the legs off a regular bike fork. The frame tubing should be pounded flat, and these inserted deep inside, then welded. The rear forks are made from 1/4" x 1" flat stock, as in fig. You may use threaded pipe as shown with the T's, or just weld it, which would be better. The lower part of the mini bike's frame is made from 1/2" pipe. Now make a simple welding jig from wood, as shown in fig.
It become the rear support for the seat.Īfter bending the gooseneck forward, cut it and the seat post so that they are both 12.5" long as measured from the top bar. Remove the rear fork as shown, but don't throw it away. If you have any qualms about the safety of the frame, build you own or find a different donor to modify. If the tubing's strength is compromised at this step, you'll end up with a possibly dangerous bike later. Heating with a propane torch will make the job easier. Bend carefully to avoid flattening the tubing. This can be done with a large jack, as shown. It's probably necessary to bend the "gooseneck" section of the frame forward to make room for the engine. Start by cutting the bike frame so you come out with the portion shown in fig. No problem, simply use the diagrams as your basis. If you can't find this, you'll have to build the frame up from scratch.
Preferably, find an old bike with a solid-feeling steel frame. You'll need to weld onto this frame, so aluminum is out. Finding a Suitable Frameįirst you'll need to find a bike frame that you can use successfuly for this project.
Though at first this sounds odd, it's really a unique idea that will save you money, and provide pre-bent handlebars, and the bearing connection at the neck.
