The 2Moto system replaces the stock swingarm and rear suspension. The front ski uses two carbide blades.
It was our friends at 2Moto that originally turned me on to the sport. While the 2Moto Radix kit was by no means the first type of snow conversion for a motorcycle, it was probably the first one to feature a sophisticated engineering concept and design.
The basic frame and track structure replace the existing swingarm of the bike. The main subframe is suspended by an Ohlins shock that takes the place of the stocker. Then the track itself rides on a secondary shock that allows it work independently of the subframe.
Unique to the 2Moto is the arced paddle track design that is higher in the center. This allows it to have a consistent feel as the machine rolls side to side. The track drives at the rear by a long chain; this couples via a jackshaft to a shorter chain section that links to the motorcycle countershaft. The airbox is removed and replaced by a cylindrical filter and Outerwear brand cover. This helps to keep the intake free of snow.
Up front steering is handled via a snowmobile style ski. The ski mounts directly to the front fork using the front brake caliper mounting holes. Additionally the ski assembly is braced by a pin that rides under the right hand fork knuckle.
The Simmons Flexi-ski uses carbides that run along each edge to help the ski track. There are also different widths available to accommodate different conditions. The 11” wide powder ski is ideal for tracking through deeper snow as it allows the ski to stay on top of the snow better. Extra mounting holes allow the ski to be moved forward or back to customize the handling. This is a way of moving the “trail” forward or back.
Riding the 2Moto Radix Kit Snow Bike
I wanted to get myself reacquainted with the Radix, so it was what I chose to ride first. The test bike was a Suzuki RM-Z450. In general the bikes of choice for conversions are those with fuel injection. This helps compensate for the vast altitude changes that come with riding in the mountains. For some reason motocrossers seem to work best for most conversions. The stock power and suspension settings tend to be just about right.
The 2Moto design works best in all-around conditions. It prefers to find powder, but can handle hard-packed trails easier than the Timbersled. None of these bikes are perfect in every situation, but the 2Moto is the most universal.
The 2Moto excels at tackling the widest range of surfaces, from powder to hard pack. The track and suspension design let it cross over between different conditions pretty well, unlike the other machines. The curved track profile allows it to make a smaller footprint on hard snow and therefore turn easier. Thanks to the shorter overall length, the suspension handles bumps and rolling whoops in a very smooth ride.
Neither the 2Moto nor the Timbersled are particularly good on groomed surfaces, though the Radix is noticeably better of the two. The ski wants to wander like the two carbide runners are constantly battling with each other – one wants to go left while the other goes right. The key is to ride on one edge or the other. In general, the 2Moto travels along an established track tolerably, but not nearly as fun as riding in fresh snow.
