The first step in modifying the scooter for off-road use is looking at the engine to see if we can generate some more power, upgrading the suspension by way of alternative forks at the front, plus a set of long-stroke shock absorbers at the rear.
The engine upgrades, should not be that much of a problem, scooter engine tuning parts are widely available in Thailand. From simple carburetor, exhaust systems, and air filter kits too complete bore-up kits, which in some cases almost double the combustion volume of the engine, are all available, the only limitation is the budget.
Modifying the ground-clearance can be a bit more tricky, for some scooters modifying shops have special kits available. In most cases changing the diameter of the wheels, and adding off-road tyres will give the desired ground-clearing.
Along with the engine, the frame has to be modified. Most underbone scooter frames are not strong and stiff enough for off-road activities, and therefore we would recommend an additional support 'strut' that has been welded on to the frame to give it extra strength.
The steering need also alteration by way of an aftermarket handlebar fitted to which, you can add a rev counter and Renthal handlebar pads.
Comparing an scootercross / off-road scooter with the road racing scooters around circuits, power isn't the biggest concern in scootercross, it's traction that's more important - “component traction must be in balance with your power. Otherwise your rear wheel will constantly spin and make steering very difficult. Most scootercross pilots have a power of perhaps 6 to 13 horsepower, if to much power and the grip on the surface is gone. For grip a good tyre selection is essential.
