railmaster XRX-300 Dune-Buggy GO-CART 300cc FUEL INJECTED water-cooled, Shaft Drive, Full padded roll-cage, 5-point shoulder harness/seat belts

TRAIL MASTER XRX300-GK 300cc FUEL INJECTED water cooled! The shaft drive go-kart is one of the most exciting and advanced buggies to come along in years! Another advantage to this shaft go-kart is the hybrid chain/shaft drive train. The output of the transmission is a chain and sprocket system that drives a small frame-mounted shaft. This small shaft in turn drives the half-shaft axles that drive the rear wheels. Why is this better? The first reason is that it easily permits the changing of final drive gear ratios by changing the size of the sprockets, like a chain drive buggy, yet it provides the durability and reliability of a shaft drive system. The second reason--related to the first--is that the chain and sprockets used are standard over-the-counter parts available at any motorcycle parts department, so aftermarket sizes are readily available at reasonable costs.


The 300cc shaft drives go-kart/dune buggy also features a sophisticated front suspension system quite similar to those found on much more expensive full-sized dune buggies and off-road vehicles costing thousands of dollars more. The XRX 300 dune buggy/kart offers superior power, torque, speed, and performance. There is an 80+% gain in power output over most go-karts and buggies in this class with the 300 XRX providing a power output of as much as 17.4 horsepower. TrailMaster XRX 300 offers an adjustable driver's seat, Aluminum alloy wheels, and an instrument board. Interior features also include the rear-view mirror, rack, pinion steering, and a rear utility rack.
