Got a set for my project bike a 12 front 48 rear on my xrx125 and it has made a lot of difference to the way the bike rides, it's not a gear setup I got for top speed I wanted more acceleration so went with a 12/48 set up now the bike not only holds it's top speed but I am able to go up hills or against head winds without changing down a gear, I can even accelerate up hills and change up gears that a normal 125 would struggle with.
Apart from the way it helps the bike run, the look of the new setup is so much better than the stock setup.
I can't say how long it will last as only done a couple hundred miles, so far it looks good.
It's a simple upgrade that's worth the money
So got this set few weeks ago as i wanted a bit longer gears. im using it in city, heavy traffic, daily commuting. Before was changing gears like a lunatic 1st to 4th non stop.. this set sorted my problem a lot to be fair. 20-35(40 with screaming engine) mph in 3rd gear. 2nd gear comfortably around 25.. unfortunately havent tried whats the max speed now as grown up life sucks and havent had time to push the bike yet
Ordered these from Norway. Fast delivery and fantastic support from the team. Bike start much easier and feels snappier in the throttle response. Fitted this together with NGK Caps and Iridium spark plugs.
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
Installed on RC 2018. Wing mirrors are excellent, exact replacement for the originals. Still maintain that sporty, angular look, as much as you can with bike mirrors. Service excellent as always from Marcel/Hyo riders team.
