MARCEL ROCKS! Not only is this kit is a must have upgrade for your bike, but the support and advice i've got from Marcel is amazing! You should now that this is my first motorcycle and I really love to make my hands dirty. I love my bike but the acceleration was a bit disappointing. I've read about a tooth more or less on the front or back sprocket, but i really didn't wanted to loose any top speed. It seemed to be one or the other (more acceleration more top speed). I talked to my dealer about this, but I didn't find any help there. So I contacted Marcel. He sent me the kit and the delivery was very fast (I live in Belgium) Then came the moment of truth: would I be able to do the upgrade myself? I succeeded with easy with some remote support from Marcel over messenger. His reaction time was very fast and I didn't loose time with the procedure if i had a question. Many thanks for that Marcel. The day after the installation came the second moment of truth. Would this upgrade perform as advertised? In short: IT DID! The test ride with these sprockets / chain exceeded my expectations . The acceleration in gears 1-4 is superb now. In second gear i can pull up to 50km/h - in 3th to 70 km/h without going in the red range! The bike pulls really fast now. About the top speed, with original chain kit my top speed was 107km/h on a steep downhill. Now on a far less steep one i reached 119 on display and gps speed was 107 !!! Speed record easily broken.

What a great kit this is!! Delivery to belgium was very quick! I'm happy with the result. Don't have to shift as mutch as with the original chain. Lower revs and more accelaration. And a higher top speed. If you buy this kit you won't regret it!! Top notch! Thanks marcel!!! Greetz from belgium

Fitted yesterday, seems to be working well, Delivery by royal mail arrived on time, Very well packaged with other items ordered, Very pleased

These brake pads are really good quality excellent service from yourselves even hand delivered way faster than expected cheers you guys

Ordered these from Norway. Super fast delivery and responses from the team during the order process. The caps together with uprated coils and iridium spark plugs have made a big difference. Cold start much easier and engine feels snappier 🙂

I just installed the kit and it’s amazing! Feels smoother And I gotta do more upgrades by roys review! I feel like slowly making this bike better and better Customer help is also 5* You guys really helped me out with all! Thank you!
