After endless voltage regulator soul searching on a 1995 BMW F650, I finally opted for an UR model. Pricier but well worth the expense: the rectifier remains barely warm, so do cables, and the tension... See more

Excellent
Put one on my Guzzi V7, it is smaller than OEM and works excellent. Fits exactly over OEM mounting points. Connectors were allready assembled and was plug and play.

Superb
Helped me choose the correct Regulator Rectifier for my BMW F650 . Order arrived quickly .
New Regulator Rectifier looks almost too good to hide away and is excellent quality . Came with all new connectors and instructions on how to wire into the motorcycle .
6 months fitted now and Voltage is rock solid and Rectifier runs significantly cooler than my old one .
Recommended.

Amazing Customer Service
We needed a part for our Aprillia motorbike. We found the part on this site but it required a bit of adjustment which we felt, if we did it would not be a perfect fit. We asked if it were possible for the company to make the adjustment. They were brilliant. Very helpful. Very informative In particular Rudy from Customer services was just excellent. Sent pictures checking first to make sure we knew what we would be receiving then kept in touch and sent pictures of it completed before sending. Just brilliant customer service. We cannot recommend this company highly enough.

Excellent rectifier
Excellent rectifier. Replaced the original Honda rectifier on a CBR 1000RR with the Ultimate Rectifier.
The UR charges way cooler than the original and shipping was very quick to Ireland.

I used your part to replace a “Rick’s Motorsports” new part that didn’t work right out of the box. Thinking the problem was elsewhere I put the bike away for 3 years then decided to buy your part. Works great now! I’m grateful for your company!

Great Rectifier ('06 Speed Triple)
Ordered a rectifier/regulator for my '06 Triumph Speed Triple 1050 and it's the first R/R I've ever had, that properly worked. 14V throughout the rev range and almost from idle (at idle it at least holds the voltage steady, with the old one you could watch the voltage drop). Shipping (to Germany) was a bit pricy but fast and considering the very reasonable price of the R/R it's still very much worth it. The R/R came with all accessories needed and a set of playing cards as a gift, which was a nice touch. I would definitely recommend this R/R to anyone looking to replace theirs.

Great customer service
Great customer service!
It turned out that my original rectifier wasn’t the problem.
The following contact with the UR customer service to return the ordered rectifier was adequate, pleasant and prompt. They refunded the full order amount. Thank you guys!
