Get the best of both worlds and hit the track with this powerful electric reverse trike. With the leaning ability and twice the torque of an avg supersport motorcycle, and double the traction and stability at the front wheels, you'll be cornering faster than the competition, and can easily navigate around obstacles on the trail.
This trike is technically a (Frankenstein) conversion, using a modified late 1980's Suzuki 250 Quadrunner chassis, and Yamaha Banshee hubs, brakes, and steering knuckles, though a Banshee or Raptor chassis would be better because it would require less modification to adapt to a leaning suspension and incorporate a swingarm (I used what I already had for parts to keep the costs as low as possible). The A arms are custom built to a certain specification to make the leaning suspension work properly, which is detailed in the plans that are available below - their geometry can be adapted to any chassis you choose, just be sure that the original steering uses Ackerman geometry and maintain it with the new design mod's, ie: make sure that the steering kingpins on each front hub point toward the center of the back wheel. All of the joints in the front suspension include high misalignment spacers where required to allow a full 30° lean in either direction. The swingarm is attached to and supports the main frame with a rear shock absorber from a Suzuki GSXR 1000 motorcycle, which includes a dog bone progressive dampening linkage (a KTM progressive dampening shock absorber is a good substitute for the GSXR shock and linkage). The plans include a full list of all of the components and materials needed to build the leaning suspension (and the rest of the trike).
The drive system uses a 12 kW/24 kWp (30 hp) electric QS hub motor mounted in a 17"x6" alloy wheel, controlled by a KLS72601-8080H programmable controller from Kelly, and powered by a 72V/4.3 kWh Li-Po battery which was custom built by GrePow. It includes a 185A/300A (peak) BMS, can handle a peak charge current of 60A for a ~1 hour charge time, and can operate in a wide temperature range, from -20°C to 60°C. |
