Item arrived quickly, with everything needed. I was sent a 13 tooth front sprocket. Have had it installed for a few days and can say while I have not seen the full speed increase (my daily commute to work is along a road with many declines and inclines) I can say that my commute is a bit quicker with this installed and I have seen higher average speeds overall. Also taking off from a stop feels better with the kit installed too. Have seen about a 3 to 5mph (speedo) increase in the gears 1-4. First time installing something like this I had all the tools needed (torque wrench, impact gun, socket set and hammer) had it done within 2 hours having read the instructions the day before so it was a straight forward and logical install (mostly need instructions for the torque specs). Only thing I had help with was holding the rear brake while torquing the front sprocket nut. Only complaint about the kit on my bike with this is that the chain adjustment needed to be set close to the maximum adjustment to remove excess slack in chain. If I have the bike when it comes time to replace the sprockets I will be purchasing this kit again.

Installed on RC 2018. Can't go wrong with NGK, the rest of the reviews have got everything spot on. Can't fault them, great starts, improved performance and great value. Can't beat it. Matt

defo good magneto and defo wakes up the bike

Just upgraded to these 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 🙂

Fitted theses and start alot easier then stock ones even at 1c outside and notice it feels more responsive

Nice shiny upgrade to the stock bearings especially after the road salt and conditions have helped my old one's to bind slightly. They feel great and didn't take much fitting very happy.

I've just got my red set and they are top quality and more solid than I expected. A big improvement on the stock ones. Five stars from me!

Just had this fitted big difference good deleviery aswel

Great improvement in gear changing and the way my gt performs now. Do yourself and your bike a favour and buy it, worth the money.
