Please select your preferred variant and the matching accessories for installation and successful operation!
This is a complete, ready-to-fit kit consisting of the rotor, the alternator coil including the corresponding mounting plate, and the alternator regulator. The kit is supplied pre-assembled with all necessary connectors.
In short: The significantly lighter rotor, with a smaller radius, results in substantially reduced gyroscopic forces on the crankshaft. The effect is immense:
- Easier direction changes, especially in chicanes
- Significantly faster matching of engine speed when downshifting under braking, resulting in:
- Faster downshifting
- Less instability, a more stable rear end
- More time and comfort when turning in
- Later braking
- Improved throttle response, faster acceleration
The typical power gain is around 5-6 bhp, though this varies from engine to engine.
This kit uses a rotor with a 45mm diameter and a weight of only 198g.
This not only reduces the effective weight on the crankshaft, as the new rotor is 78% lighter than the original rotor (890g), but above all the gyroscopic forces are reduced thanks to the significantly smaller radius of 45mm instead of 120mm. Here is an example to illustrate the effect: at 14,000 rpm, a standard rotor reaches a rotational speed of 320 km/h due to its larger radius, whereas the kit rotor reaches only 120 km/h.
The main performance benefits stem from the fact that a lighter rotor with 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, resulting in uneven and relatively low output. In addition, the original regulator is often retained, which is not designed for the excess power generated at the required revs and can only convert this into damaging 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, consistent power from lower revs onwards (approx. 4,000 rpm).
Another clever feature lies in the switching system of our special alternator regulator. Once the desired voltage is reached, no further electricity is generated at the crankshaft. This results in a significantly cooler and more durable regulator. For this reason, you should never use our alternator kits with the original regulator.
Particularly in view of the specific requirements regarding the necessary capacity reserves in conjunction with a racing alternator, we recommend using a LiFePO4 supply battery with a minimum of 7.5 Ah, preferably 10 Ah.
We advise against using a lithium polymer battery in combination with a racing alternator.
To remove the original flywheel, you will need a puller.
Pullers and LiFePO4 batteries are available here in the shop.
Important installation notice
for racing alternator kits from BDK Race Engineering
A BDK racing alternator kit replaces your motorcycle's rotor, stator and regulator/rectifier with a significantly lighter unit designed for racing use. This provides a noticeable reduction in rotating mass – but requires careful installation and involves changed operating behaviour. To ensure your kit works reliably from the outset, here is an overview of the most important points.
Who should carry out the installation?
Installation should be carried out by an experienced mechanic – someone who is confident working on the engine and the vehicle's electrical system. Specifically, this includes:
- Removal of the alternator cover, flywheel/rotor, starter clutch and stator, including securing the Woodruff key (rotor key)
- Removal and refitting of the ignition pulse sensor (pickup), maintaining the original installation position
- Working with thread locker and specified torque values according to the manufacturer's instructions
- Cleaning sealing surfaces, correctly fitting new gaskets and locating dowels, and sealing the cable grommet
- Professional crimping of the spade connectors and fitting of the connector housing
- Connection and fusing of the regulator/rectifier in the vehicle electrical system, plus measurements with a multimeter in AC and DC
What matters during installation
- Thread locker is mandatory: All screws must be fitted with thread locker and tightened to the specified torque. Failures have already occurred due to missing thread locker – this is the most common avoidable mistake.
- Only use the supplied regulator: The standard regulator must never be used with a racing alternator. The regulator body must have a permanently clean earth connection.
- Regulator mounting: on a flat metal surface exposed to airflow, away from exhaust heat. One mounting point bolted, the second secured with a cable tie.
- Pay attention to cable management: Route the stator and pickup wires and secure them with the original clamps as done from the factory – free of chafing, with sufficient movement clearance, and not pinched. A chafed cable causes a short to earth.
- Connectors: Every spade connector must click audibly into place. The order of the three stator wires is not important – a secure fit is what counts.
- Fusing and switched positive: An intact fuse (30 or 35 A depending on kit) must be fitted in the positive line. The signal wire must be connected to a switched 12V positive supply so that no standing current flows when parked.
- Follow the original installation instructions: Sequence, torque values, gasket part numbers and cable lengths are model-specific and are detailed in the enclosed BDK instructions.
What changes during operation
A racing alternator deliberately delivers less charging output than the standard system. Depending on the kit, it only starts charging from around 3,000 to 5,000 rpm; prolonged running at lower engine speeds will discharge the battery. This results in three fixed rules:
- Always start with a fully charged battery, using at least a 7.8 Ah LiFePO4 battery, ideally 10.4 Ah.
- After each session, remove the fuse at the regulator, disconnect the 12V supply, or use a battery disconnect switch – otherwise deep discharge may occur.
- Never start or run the bike with the battery disconnected or the regulator unplugged. This will damage the alternator.
The green LED on the regulator indicates that charging is taking place – a useful quick check before and after each session.
Diagnostics
The installer should be able to independently check with a multimeter: the fuse and switched positive supply, continuity between the stator pins (present between each other, none to earth), the AC voltage between the stator pins at a constant engine speed, and the charging voltage at the battery. This allows almost all faults to be narrowed down within a few minutes – often to something minor such as a blown fuse or a connector that hasn't clicked into place. The specific target values can be found in the troubleshooting section of the enclosed instructions.
If you're unsure
That's not a problem – in this case, please have the installation carried out by a specialist workshop or an experienced racing mechanic. If you have any technical questions about your kit, we'll be happy to help; just get in touch with us.

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.
