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. Our regulator features a 20-turn potentiometer for adjusting the maximum output voltage (counter-clockwise increases the output voltage).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.

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 race alternator kit consisting of the rotor, stator, mounting plate and the dedicated regulator/rectifier. The kit is supplied pre-assembled with all necessary connectors.In short: the significantly lighter rotor with a much smaller radius results in drastically reduced gyroscopic forces acting on the crankshaft. The effect is immense: Easier direction changes, especially in quick chicane transitionsMuch faster engine-speed matching when downshifting under braking, resulting in:quicker downshiftsless chassis disturbance, improved rear-end stabilitymore time and confidence when turning inlater brakingImproved throttle response and faster accelerationA typical power gain is around 5–6 hp, although this varies slightly from engine to engine.The kit uses a compact 45 mm rotor weighing only 198 g. This not only reduces the effective rotating mass on the crankshaft—since the new rotor is 78% lighter than the OEM unit (198 g vs. 890 g)—but more importantly reduces gyroscopic forces thanks to the much smaller radius (45 mm vs. 120 mm). For comparison: at 14,000 rpm the OEM rotor reaches a tangential speed of approx. 320 km/h, while the race rotor spins at only about 120 km/h.The key performance advantage comes from the fact that a lighter rotor with a smaller radius is far easier to accelerate and decelerate.Most racing alternators also use a smaller rotor, but typically with far fewer windings. This results in low and inconsistent output, and they still rely on the OEM regulator—which is not designed to handle surplus power at racing rpm and converts it into damaging heat. Our alternator kits also feature a compact rotor, but we use high-efficiency, fine-gauge copper wire for the windings. This enables us to deliver strong and consistent power from lower speeds (approx. 4000 rpm).Another key benefit is the intelligent switching system inside our dedicated regulator/rectifier. Once the required voltage is reached, no additional electrical load is generated at the crankshaft. This keeps the regulator significantly cooler and far more reliable. For this reason, never use our race alternator kits with the OEM regulator.

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 comes pre-wired 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 turnsMuch quicker adjustment of engine speed when downshifting in the braking zone, resulting in:Faster downshiftingLess instability, more stable rear endMore time and comfort when turning inLater brakingImproved response to throttle commands, faster acceleration The typical increase in power is approximately 5-6 horsepower, but varies from engine to engine. In this kit, a rotor with a 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 essential performance effects stem from the fact that a lighter rotor, which also has a significantly smaller radius, is much easier to accelerate and decelerate. Our alternator kits also use a small rotor, but we use a particularly efficient and fine wire for our windings. This allows us to provide strong and consistent power at lower revs, but the clever part is in the reg/rec. Another highlight lies in 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 special requirements regarding necessary capacity reserves in conjunction with a Racing Alternator, we recommend the use of a LiFePo4 supply battery with at least 7.5 Ah, preferably 10Ah.When using a Racing Alternator, we advise against the use of a Lithium Polymer battery.To remove the original flywheel, you will need a puller.Pullers and LiFePO4 batteries are available here in the shop.

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 race alternator kit consisting of the rotor, stator, mounting plate and the dedicated regulator/rectifier. The kit is supplied pre-assembled with all necessary connectors.In short: the significantly lighter rotor with a much smaller radius results in drastically reduced gyroscopic forces acting on the crankshaft. The effect is immense: Easier direction changes, especially in quick chicane transitionsMuch faster engine-speed matching when downshifting under braking, resulting in:quicker downshiftsless chassis disturbance, improved rear-end stabilitymore time and confidence when turning inlater brakingImproved throttle response and faster accelerationA typical power gain is around 5–6 hp, although this varies slightly from engine to engine.The kit uses a compact 45 mm rotor weighing only 198 g. This not only reduces the effective rotating mass on the crankshaft—since the new rotor is 78% lighter than the OEM unit (198 g vs. 890 g)—but more importantly reduces gyroscopic forces thanks to the much smaller radius (45 mm vs. 120 mm). For comparison: at 14,000 rpm the OEM rotor reaches a tangential speed of approx. 320 km/h, while the race rotor spins at only about 120 km/h.The key performance advantage comes from the fact that a lighter rotor with a smaller radius is far easier to accelerate and decelerate.Most racing alternators also use a smaller rotor, but typically with far fewer windings. This results in low and inconsistent output, and they still rely on the OEM regulator—which is not designed to handle surplus power at racing rpm and converts it into damaging heat. Our alternator kits also use a small rotor, but we use a particularly efficient and fine wire for our windings. This enables us to deliver strong and consistent power from as low as 4000 rpm.Another key benefit is the intelligent switching system inside our dedicated regulator/rectifier. Once the required voltage is reached, no additional electrical load is generated at the crankshaft. This keeps the regulator significantly cooler and far more reliable. For this reason, never use our race alternator kits with the OEM regulator.
