The stock Burromax motor is stout, but the narrow motor cradle in the swingarm makes it impossible to install any upgraded motors. We have tried placing the motor everyway we could, and this is the only way we could do it without virtually re-designing the entire swingarm.
Momentum Watts has modified the original swingarm to work with Sotion FW11, Electro and Co EC4P, EC5P, The ONE, Kunray KR5V, or any other MY1020 style motor.
Sold as a complete swing arm with brackets welded in. The bracket has a multiple holes so that you can orient/clock your motor as needed. Does NOT include a motor, but can be purchased from us as well.
DISCLAIMER: This new swingarm WILL make the motor sit much closer to the ground, we do not condone using this upgrade for off-road riders, this is more an upgrade for private pavement use due to the decreased ground clearance. Use at your own risk.
