Compatibility of our rectifiers with Suzuki motorcycles

Compatibility of our rectifiers with Suzuki motorcycles

Our Solvart regulator rectifier is compatible with nearly every Suzuki motorcycle. The only requirement for compatibility is that the motorcycle has a three-phase generator, which you can easily check even as a layperson.

If three phase (yellow or black) wires are coming from the generator towards the regulator rectifier, then your generator is three-phase and suitable for our three-phase MOSFET regulator rectifier. If you're unsure because fewer than three wires are coming from the generator or you're uncertain about the type of regulator you need, please contact us at info@rectifier.eu

Is it really that simple? Essentially, yes!

The operating principle of (three-phase) regulator rectifiers is the same regardless of the type of motorcycle they are used with.

However, it is true that a regulator rectifier designed for a smaller capacity generator (where the heatsink is smaller and can fit into tighter spaces) may not be able to handle a 500W generator. Additionally, there are custom connectors and different wiring configurations. Because of these factors, you may often see voltage regulator units labeled specifically for certain motorcycle models like the Suzuki DL 1000 on other websites. This can be beneficial if you prioritize plug-and-play functionality (meaning you can simply plug it in and it works).

Our product may require a bit more effort to install from this perspective, but in return, it is much more affordable compared to OEM (original) or the high-quality (non-Chinese!) aftermarket regulators. It is specifically designed for high-power generators, capable of handling a range from large scooters (e.g., Suzuki Burgman AN 400) up to generators used in bikes like the Suzuki GSX 1300 Hayabusa. Additionally, we provide detailed descriptions to help you determine if the regulator is indeed the issue, and we offer professional assistance for any questions you may have. 

But then what should I pay attention to when ordering and installing a motorcycle regulator rectifier?

  1. Our voltage regulator comes in two types: 5-wire or 7-wire. The difference between them is that the 7-wire version has duplicated current outputs (two positive and two negative wires coming out of the regulator). This duplication is necessary because of the high current flowing through the wires; by doubling them, it increases the total diameter of the wires, reducing the load on each wire and lowering heat generation within the wires for added safety. 

So basically, it's fortunate if you order yourself a regulator with the wires like the one it had before, but (for example) you can make a 5-wire regulator out of a 7-wire one, which still perfectly serves its function, see FAQ point 7. Based on previous orders, we see that for Suzuki SV 650 and Suzuki GS 500, only a 5-wire regulator was installed. However, be sure to check how many wires the (old) regulator rectifier (which is) currently installed on your bike has. For example, regulators for Suzuki GSXR 600 or Suzuki GSXR 750, both 5-wire and 7-wire types were often used, so it's likely dependent on the model year how the connection is made to the battery (with solo current wires (5-wire type) or with doubled current wires (7-wire type))

  1. You can also choose the length of the wiring. Typically, a "standard" 25 cm wire is sufficient, but if you've relocated the regulator rectifier elsewhere (e.g., for better ventilation), you can request a longer wire from us (approximately 55 cm in length).


  2. In Suzuki motorcycles, an ignition-switched positive wire is not typical. In the case of the Suzuki GSX 1400, we have seen such an additional wire, which is usually a thinner brown or black wire. It is very easy to identify with a multimeter: when the ignition is on, it shows the battery voltage; when you turn off the ignition, it disappears. If your bike also has such an additional wire, you can read more about it in FAQ point 8.

    In case of our Solvart voltage regulator, there is no ignition-switched positive wire; the regulator handles this differently. Essentially, if your old rectifier had 6 wires (with the ignition-switched positive wire), then our 5-wire regulator will be suitable for your motorcycle, and you should "exclude" the ignition-switched positive wire (of the motorcycle's side) and insulate it with insulating tape.
