Please select the appropriate model year for your model, as well as the suitable accessories for installation and successful operation! This is a complete ready-to-install kit, consisting of the rotor, the alternator coil including its mounting plate, and the alternator regulator. The kit is supplied pre-assembled with all necessary connectors. In short: The significantly lighter and smaller radius rotor leads to significantly reduced gyroscopic forces on the crankshaft. The effect is immense: Easier leaning, especially in switchback turnssignificantly faster engine speed adjustment when downshifting in the braking zone, resulting in:faster downshiftingless instability, more stable rear endmore time and comfort when corneringlater brakingimproved response to throttle commands, faster acceleration The typical power increase is about 5-6 horsepower, but varies from engine to engine. In this kit, a rotor with 45mm diameter and a weight of only 198g is used. This not only reduces the effective weight of the crankshaft, as the new rotor is 78% lighter than the original rotor (890g), but above all, the gyroscopic forces are reduced by the significantly smaller radius of 45mm instead of 120mm. An example to illustrate the effects: A standard rotor at 14000 rpm, due to its larger radius, has a rotational speed of 320 km/h, while the kit rotor only reaches 120 km/h. The main performance effects stem from the fact that a lighter rotor, which also has a significantly smaller radius, is much easier to accelerate and decelerate. Most racing alternators also use a smaller rotor, but compared to ours, usually with significantly fewer windings in the coil, so that uneven and relatively low power is generated. In addition, the original regulator is still used, which is not designed for excess power at the necessary speeds and can then only convert this into harmful heat. Our alternator kits also use a small rotor, but we use a particularly efficient and fine wire for our windings. This allows us to deliver strong and consistent power from lower speeds (approx. 4000 rpm). Another highlight here is the switching system of our special alternator regulator. As soon as the desired voltage is achieved, no further electricity is generated at the crankshaft. This leads to a significantly cooler and more stable regulator. Therefore, never use our alternator kits with the original regulator. Especially for the particular demands regarding necessary capacity reserves in conjunction with a racing alternator, we recommend using a LiFePo4 supply battery with a minimum of 7.5 Ah, preferably 10Ah. We advise against using a lithium polymer battery when using a racing alternator. To remove the original flywheel, you will need a puller. Pullers and LiFePO4 batteries are available here in the shop.

In addition, the original regulator is still used, which is not designed for excess power at the necessary speeds and can then only convert this into harmful heat.Our alternator kits use smaller rotors with particularly effective magnets and a highly efficient wire winding of the coil. This allows us to deliver strong and consistent power from lower speeds (approx. 4000 rpm).Another highlight here is the switching system of our special alternator regulator. As soon as the desired voltage is achieved, no further electricity is generated at the crankshaft. This leads to a significantly cooler and more stable regulator. Therefore, never use our alternator kits with the original regulator.
