KTM 790 / 890 21+ Race Alternator Kit    Ordering No. RG-KTM79089021

This is the complete race generator kit including the lightweight flywheel, stator, mounting plate, cup, fasteners, connectors and specific regulator / rectifier.

Significantly lighter than standard, offering higher output than 'race kit' versions, providing increased throttle response,less gyroscopic forces and more bhp everywhere.  It is designed to fit high performance injection engines, and as a replacement for standard alternator systems.

With fuel injected bikes the option to run a 'total loss' system has become impossible, due to the drains from fuel pumps and injectors.  The standard alternators are designed to run headlights etc and need to be able to supply significantly more power than you will ever need on a race bike.  This means you can use a considerably smaller system, reducing the weight of the crankshaft assembly.  

Most race kit generators have a smaller rotor with less windings running single phase in the stator so that they produce less outright power (and accordingly take less power from the crank to generate the electricity), but use a standard reg/rec.

The problem with this is that you have to rev the engine quite hard to produce any useable power and any excess electricity created is still converted to heat in the reg/rec and thrown out the back of the bike.

Our generators also use a small rotor but our windings have a lot of turns of fine wire.  This allows us to provide strong and consistent power at lower revs, but the clever part is in the reg/rec.  The reg/rec contains a switching system which cuts the generating power when the desired voltage is reached and therefore the power is not taken from the crank to convert to electricity in the first place.  This is why our reg/recs run much cooler than standard models and why you cannot use our generators with a standard reg/rec as the generator would be under load all the time creating excessive heat in the windings.

Especially for the special demands regarding necessary reserve capacity in connection with a racing alternator we recommend the use of a LiFePo4 supply battery.

Comfort upgrade of the racing alternator regulator

This is a comfort modification of the racing alternator regulator. This relay upgrade eliminates the need to disconnect the battery after using the motorcycle on the race track
due to the continuous running of the voltage measurement circuit.

New customers add this article in addition to the desired racing generator in the cart and get a modified regulator shipped.

If you have already purchased your racing genaerator in from us or from another supplier, then of course we need your removed regulator unit. You will receive a modified regulator back within a processing time of 4-6 working days.

All customers who have bought their racing-alternator from us and would like to request a modification please contact us via email.

Spare Part: Regulator for Racing Alternator                                      ORDER-No. RG-LMREG

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.

Sparepart Stator RS5 for racing alterantor generator Kits          
Order Nr. SPSTATORRS5

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!
