Genuine Yamaha NMAX NVX 125 - MBK Ocito Big Bore Cylinder Kit 155cc

Genuine Yamaha 155 Kit

Contains everything you need to make a 125cc Nmax into the 155cc version. Installation was very simple and I am not a mechanic. The parts contained in the box are genuine Yamaha Factory parts. After install the bike feels much more lively and very responsive compared to when it was 125. Fuel economy is now at 104mpg after 119 miles, may require a longer run in time. I have just completed my first oil change after the install and there were very few metal debris in the oil filter.
I would buy this kit again if I had another Nmax 125, so far there are no bad points about buying this kit.Read full review
