If you're running up to 200 line amps this is the kit for your GTS or FW11. This will only work on the Midwest Mini Mods swingarm. Depending on torque settings, you may need to run less power, if the belt is skipping and tensioned properly you may have to reduce power eliminate any skipping. We have not done much testing and will need your feedback on power you're running and how it's handling it!
These belt systems are meant for street use only. Please be sure to properly tension these belts and recheck them after the first few hard rides to make sure they have not stretched and gotten loose. This kit includes a 18mm wide belt, a 90-120 tooth rear pulley option, and a 20 tooth motor pulley. Belt brand will vary depending on our stock. These will only work on pit bike wheels that we sell or the same mounting pattern from elsewhere.
Please also note that since Sotion messed up the design of the GTS11 and it is 3mm longer than a my1020, it does move the pulley over 3mm. We are working on a 3mm plate to push the sprocket or pulley over 3mm on the rear wheel for owners of this model.
