Ultimaterectifier レビュー 

Great customer service, and communication is clear, helping me to decide options available to me.
Ordering and shipping to UK was fairly quick.

Quality rectifiers and wiring SKU: UR-SR-121-230 for my 98 Honda VFR800FI to replace my failed unit, providing a stable voltage though idle to high rpm as indicated by my voltage meter that was connected.

Would highly recommend!

Merel and the team at Ultimaterectifier were excellent from the very start to the very end. They got back to me quickly with my initial enquiry and I could tell that they really knew their stuff (which filled me with confidence). A couple more questions were answered quickly and then my order was placed. It arrived swiftly, I fitted it and it cured an ongoing problem where previous inferior products had failed. Merel and the team are genuine and professional. It was so refreshing to experience the human touch for a change. I would thoroughly recommend them. Great work!

Service at this company is just magic
The product vs price is good

Have bought them for both my motorcycles

Recommended 👍👍👍👍

Very good customer service answer came within a day of writing they helped a lot with my numerous questions.
I ended up ordering a different one than what they recommended a ur 104 for a Honda vfr 800 2001 for my KTM 640 2004 so I could make my own cables.
The rectifier looks good I can't test it so far as the bike is in storage but the delivery was fast it came in 3 days and the plugs fit very well was easy to install and didn't hit the negative battery post like the original did.
Very nice people at customer support when i asked if they sell extra crimps in case they break they offered to send new ones I will make sure to recommend them to friends.

Update 2026 I ordered 3 new connectors to have spares after i accidentally broke the locking tab on one of them i ordered on a sunday and the delivery is only 3 days later.
Really fast delivery thanks once more for the parts.

Well, what can I say. Brilliant customer service.
Original product arrived in good time and was simple and easy to fit, (BMW F800 st). After a few months I had a failure and the Rudy and team quickly replaced the unit. However there was a slight issue with the plug on this unit (I would suggest this to be a supplier issue rather than UR) and although it was difficult to show/explain the unit was replaced in good faith.
So the number of units they probably sell it’s reasonable to think a percentage won’t be perfect as any company selling a product but it’s how a company deals with these issues is what I value and I think they have done a great job. I will say, I used the WhatsApp option as method of contact and they have always responded, even when I simply sent a video demonstrating my issue and they still responded to show a little gratitude as now they know they can rectify issues or as a company deal with it. So I have to say I’m happy I chose UR.
Thanks you.

Website and ordering was fine, product not so much.

Having a 1994 VFR750, new to me, which is known for charging issues I decided to do a preventative upgrade to the 'Ultimate'.
6 months and max of 2,000km later it dies leaving me at the side of the road with a huge recovery bill.
Putting the old un-branded one back on when I got home of course restored normal operation.

Emails asking about the '3 year warranty' go unanswered so it seems like the warranty isn't worth the pixels its written on.

Update- They got back to me with a return label. I had been responding to receipt emails which turned out to be a no-reply.

Nadat de nieuwe UR spanningsregelaar op de motor was gemonteerd bleek deze niet goed te werken. Contact gezocht met de leverancier (Rudy) en samen gezocht naar mogelijke oorzaken. Niet gevonden en terstond werd een ieuwe opgestuurd die het prima deed. Uitstekende service!

I ordered a custom wire length rectifier to fit my Ducati 1098s.

Rudy and the Ultimaterectifier Team are very professional and a pleasure to work with.

The new unit is doing an outstanding job putting out 14.55v at 1200rpm and unlike the OEM unit runs completely cool to the touch.

I placed an order for a Vfr 750 rectifier on the 18/08/25 it’s supposed to take 5 to nine days,the order says complete on their website no shipping date,I have tried ringing and the number doesn’t exist. They are a big con don’t bother it’s a big scam !

Perfect! Needed a new rectifier/regulator for my 2003 Aprilia Caponord. UR's plug and play model fitted perfectly and gives a steady 14,5 volt at idling rpm. High quality looks and feels, very happy

Perfect customer service. Very helpfull in finding the right model for my bike. Well finished product that seems to work perfectly. Nice experience buying from someone who puts quality first.

I Purchased an ultimate rectifier for my 2008 Daytona 675 in December 24, fitted it and started using my bike in March 25, this month august 25, I had some troubles with the charging system with my bike. I emailed ultimate rectifier not sure if it was related to that, Rudy Coppens of customer services was super fast to reply with information and I soon realised it wasn’t the rectifier that was the problem and the bike is now fixed. I would definitely buy from this company again and would recommend it to friends. Customer service is top notch and you don’t see this often now. Thanks again.

Ich hatte an meiner Suzuki Gsxr 750 ein Problem mit der Steckverbindung zur Lichtmaschine. Ich habe mit UR kontaktiert und ihnen mitgeteilt, dass der Stecker schmelzen könnte. Mir wurde hier sehr schnell geholfen. Ich habe es gar nicht angesprochen doch UR hat von sich aus mir einen neuen kompletten Rectifier geschickt. Das finde wirklich toll und einen schnellen Service. Herr Coppens war ein sehr freundlicher und hilfsbereiter Ansprechpartner. Vielen Dank für die tolle Unterstützung.
Mit freundlichen Grüßen

I have yet to test the rectifier and will comment about after some extensive riding. But I can already say the customer service is awsome.
Shipment of the first order was quick, unfortunately the mail service in Austria lost the package, I made a second order and informed the customer service - they immediately replied very kindly - filed their own inquiry - and shipped the second order out instantly.
Thank you, Rudy!

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.

cette entreprise est très professionnel et très à l'écoute des clients ,je n'ai jamais trouvé un commerce en ligne aussi communiquant et très réactif , une volonté de satisfaire !

Als liefhebber van oude motoren en docent motorvoertuigtechniek kijk ik met andere ogen naar de motoren die ik ooit aangeschaft heb. Ik heb er nu 9. Normaal laat ik een motor met permanente magneet dynamo staan vanwege onbetrouwbare inefficiënte spanningsregeling, waarbij altijd veel hitte ontwikkeld wordt! Vroeg of laat gaan daardoor regelaar en vaak ook de stator kapot. De serieregelaar van Ultimate Rectifier werkt op een ander principe. Nog nooit zo'n stabiele laadspanning gezien met een regelaar die niet eens warm wordt! Super!!

Goede kwaliteit regelaars en de klanten service is in 1 woord top.

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 .

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.
