I’m extremely pleased with the restoration of my CZ100. From start to finish, the whole process was handled professionally, with great attention to detail and obvious pride in the work. The quality of the restoration is excellent, and the finished result has completely transformed the appearance of my CZ100. It looks fantastic and has been brought back to a really high standard. You can clearly see the time, care and effort that has gone into every part of the job. Communication throughout was also excellent, and everything was explained clearly. It’s always reassuring when you know your item is being looked after properly, and that was certainly the case here. I’m genuinely very happy with the finished result and would have no hesitation in recommending Cliff to anyone.

Big big thanks for brilliant work on my 1962 Honda C100! There was nothing particularly wrong with the bike, just a tad tired after the best part of 65 years. We decided we'd start with an engine strip down and rebuild. I was keen to preserve to patina of the bike and not have the engine so shiny and bright on the case it looked out of place. In the process I said go ahead and fix anything else that needed fixing, so great to have indicators (6v were never going to be the brightest but they were "faint"), brakes that don't feel like custard and bits and bobs I'd long run out of talent. The result is brilliant - it 'looks;' exactly like the bike I delivered but feels great to ride - not least the confidence it inspires to know the engine is fresh, I can stop and don't have to keep sticking my arm out at junctions. A very satisfied customer. Great communication throughout and great service!!

Cliff offers the perfect blend of skilled, affordable work and an approachable can-do attitude. He spent many hours rebuilding and restoring my old PC50 engine, not one that he normally deals with. The end result was a beautiful work of art, but sadly still had some oil burning issues. Between the two of us we worked out a fix and I returned the engine to him. After some head scratching and research he solved the issue. My engine now runs as beautifully as it looks. Thanks Cliff. Great job.

Cliff is absolutely superb!! Both as a mechanic and as a human being. I was at the end of my restoration of a chrome Z50J and the engine had been buggered. Basically took it to Cliff in bits and asked him for his help in figuring out which parts belonged to the engine and which not, as it had been put together previously with a mismatch of things. Cliff not only sorted the engine out in 3 days but also went over the whole bike and addressed everything else he could spot. No need to say that I'll be visiting him soon for some further work and upgrades.

I recently had my 1981 Honda Z50J repaired and restored by Cliff at Monkey Bike Repairs, and I couldn’t be more impressed. From start to finish, the entire process was seamless and professional. Cliff is truly a master of his craft, bringing the bike back to its former glory with precision and care. What stood out the most was his clear and consistent communication. He kept me updated every step of the way, consulting me on the road map for the restoration and sharing progress photos, which gave me total confidence in the process. Despite the logistics of sending the bike via van and coordinating an out-of-hours delivery, Cliff was incredibly cooperative and easy to deal with, going above and beyond to accommodate my situation. On top of that, the pricing was far more competitive than I expected, especially given the exceptional quality of his work. The value for money is unmatched. The quality of his work is second to none, and I can confidently say he is one of the best motorcycle mechanics I’ve ever had the pleasure of working with. If you’re looking for expertise, reliability, outstanding service, and great value, look no further than Monkey Bike Repairs. Highly recommended!

One word fantastic, Cliff was extremely helpful from the very first phone call about the problems I was having with my 1963 Honda CZ100 engine. He worked on my engine at his workshop and got her running sweetly. Price was very competitive, very fast turnaround and the after sales support was excellent. His knowledge of Honda monkey bikes and other classic Hondas is outstanding. I can’t thank him enough for all the help and support, would highly recommend him to anyone. Thank you Cliff 🏍️

Cliff at Monkey Bike Repairs did an outstanding job of restoring my Dad's old Honda ST70 for me. It's a very sentimental item to me which he totally understood and I couldn't be happier with it. The work was done very quickly, to a very high standard and fairly priced. Cliff's a very friendly chap who gives you total confidence in what he does. Highly recommend.
