It really does make big difference I’m just not sure about the front sprocket Because I see the one on shop it has 14teeth I recited 13teeth But I’m very happy about this upgrade 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.

Starting with the quality of the wire work, excellently put together. As for longevity, I made this switch around 4k miles when my stock regulator went out. I decided to just replace the stator as well. (The stator provided by Marcel was a ElectroSport USA stator] It has been three years since I've had these parts and they have continued to hold up. I blew one regulator fuse(THANK YOU) and that is from pushing the bike to the absolutely limit(6 months ago) on a speedrun to get to an Autoparts shop for a drainplug for my car before they closed. If you are looking to replace the stock reg and stator I would trust the work put out here. They know where to find quality parts. If it wasn't for wanting to not mess with this again, I would pick up a Shinden set that is still floating around here.

Arrived super fast. Plugged in my 125p started the engine, took it out for a ride, amazing indeed, instant noticeable improvement to start up, idle, throttle response 🤗 perfect. Thanks.

Get these Laser Iridium Spark Plugs everyone, in Combination with the NGK HT Leads, it makes a difference, she runs a lot smoother, better Throttle control and idle

Bought these EGR blanking plates the other week and they look spot on, were delivered quick too. I'll upload a picture once I've rebuilt the engine. Cheers
