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 turns
- significantly faster engine speed adjustment when downshifting in the braking zone, resulting in:
- faster downshifting
- less instability, more stable rear end
- more time and comfort when cornering
- later braking
- improved 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.

COMPLEMENTARY ACCESSORIES & SPAREPARTS
SPAREPART STATOR FOR RACING ALTERNATORS This is the basic stator only intended as a replacement part for those who are confident in wiring and fitting or including the statorcup and stator installation from us. Please choose in the options! For DIY-Buyers: The damaged stator can be removed by being pressed out. Take note of where the stator wires should end up in relation to the stator cup fixing holes and heat the stator cup on a hotplate or similar - the stator should then drop in. Please ensure that the wires do not touch the hot stator cup and that the stator finishes flush and fully home in the cup. The stator core should only just be visible over the edge of the stator cup. Once cool the sheathing, grommet and connector block can be recovered but fresh crimps will be required. Please note some early model generators had a slightly different size stator, in this cases please order with stator cup!
Spare Part: Regulator for Racing Alternator 3 Phase Regulator/Rectifier. Every year a high number of alternators fail due to lack of heat transfer and cooling. One reason for this is imbedded in the design of many Japanese and aftermarket regulators. They work by short circuiting the generator, and by doing so the regulator is running at 100% capacity all the time. This way the excess power produced at high rpm by the generator is transferred from electrical energy to heat in the alternator and the regulator. Our regulators work by disconnecting the alternator from the regulator when there is sufficient voltage in the battery. Because the alternator is running without any load it produces less heat and resistance. This design lengthens the life of both the alternator and the regulator, and less resistance on the engine (= more power). The ultimate output of the regulator voltage is adjustable and this product is suitable for use with all types of Lithium racing batteries. There is an LED fitted to the regulator which shows when the regulator is overcoming load on the system. This will work with ALL types of 3 phase alternators and generators. The 3 phase Regulator/Rectifier MUST run with a battery at ALL times. Connection: The regulator is connected to the alternator by the 3 wires in no particular order. The red wire is connected to the battery +ve, via a fuse (fitted). The black wire is connected to the battery –ve. The housing of the rectifier has to be earthed with fitting directly to the body or with an extra wire. The thin blue wire is connected to a switched +ve 12V supply (so no drain occurs when the vehicle is off). You cannot test or run the regulator without the battery connected. The battery and alternator must be charged and in good working order. Always ensure the battery is fully charged before starting. When mounting the regulator please ensure there is good airflow and as much space as possible around it. Spacers behind the regulator will allow extra airflow behind it.
You are ordering a RACEPACE LiFePO4 Endurance Power battery – a high-performance battery system consistently engineered for racing applications. The focus is on electrical stability, repeatable power delivery and maximum reliability under heat, vibration and high current peaks. Compared to conventional motorcycle batteries, the Endurance Power series offers up to 75 % weight reduction while providing significantly higher performance and a substantially extended service life. Polyimide-insulated individual cells – stable electrical safetyEach individual 26650 cylindrical cell is equipped with a high-temperature, electrically stable polyimide insulation layer. This ensures permanently consistent electrical isolation even under thermal stress, vibration and tightly packed cell configurations. Unlike conventional PVC insulation, polyimide maintains its insulation properties across a very wide temperature range and throughout the entire service life – a decisive advantage in racing environments. Copper busbars & precision spot weldingCell interconnections are realized using low-resistance copper busbars, joined by a transistor-controlled bipolar spot-welding machine. Pneumatically regulated electrode pressure ensures reproducible weld quality with minimal thermal stress on the cells. Active cell balancing & external fine-balancing portAn integrated active balancer continuously monitors all cell voltages and intervenes from a voltage difference of just 0.1 V – even during charging. Cells are actively balanced down to approximately 0.01 V. In addition, an external balancing port allows targeted fine balancing using smart chargers. Fine balancing is recommended once per race weekend. Robust, high-temperature & impact-resistant enclosureThe newly developed enclosure is manufactured from a high-performance engineering polymer offering excellent temperature resistance, high impact strength and long-term dimensional stability. It reliably protects the battery pack from mechanical and thermal stress under real racing conditions. Manufactory quality – Made in GermanyEach RACEPACE Endurance Power battery pack is manually assembled and tested. The result is not a mass-produced product, but a deliberately over-engineered high-performance energy system.

2-piece puller for racing alternator rotorWhen pulling rotors with the two-piece puller: First, carefully remove the aluminum threaded washer (with nut head). With newer versions, removing the nut/threaded washer is not necessary, as sufficient thread is available. Engage the outer puller completely. Tighten the central puller bolt until the rotor is released. On some models, the bolt securing the rotor may need to be loosened so that the puller can press against it to release it.
