Wow such a huge difference, finally changed this myself. Not too scary. Straight swap for old kit. Didn't even need a gasket. Much sharper gear changes and acceleration. I highly recommend. On a scale of 1 to 10 it's about a 6 in mechanical knowledge. Remember to soak the plates and don't over tighten the bolts. It's a full oil change so have at least 2 litres handy

Fantastic service from marcel. Brilliant bit of kit and would recommend anyone looking to upgrade to buy this kit.

Bought and Installed on RC 2018. Excellent strength, the full kit that is provided is excellent value for money and much better than other providers. Sprocket especially is a great upgrade. Visually it looks great, I will aim to get some photos added to show final product.

Absolutely amazing. Really perked the bike up. It has never felt so alive. And it's so nice not having to use choke as now with these it just fires up and idles perfectly

Much better quality than oe items, fitted perfectly, much smoother and performance gains noticeable instantly, well worth the money. thanks Marcel.

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.

Recently fitted this clutch kit and I as well as the customer are extremely happy with the parts not only that the help and feedback was fantastic. Don’t waste your time on other sites use these guys for top quality parts with speedy delivery and 10/10 customer service.

Just had this fitted big difference good deleviery aswel

Just upgraded to the uprated coils, the uprated regulator, the uprated stator and ngk caps with iridium spark plugs. I have to say it made an amazing difference, the bike almost no longer needs choke (less than a minute and only on first start in the morning), acceleration has improved significantly and my bike is now charging (which was my original problem :p). Very happy with all items 🙂 Bike is a 2003 gv250 carby model

Life changing part of you are looking to change coils. I’ve put my new coils through a lot during the problematic idle and power problems. Works so well with the regulator you can purchase here. A total must have.
