Piston 47mm 70cm3 4T 139FMB set

This is the first time I've ordered a piston from this site, and I have to say that I'm clearly not disappointed. The piston is in very good condition, there's no trace of scratches or anything else, plus everything is very well packaged, nothing to say on that score, and the rings fit superbly, they're not damaged or broken at all, nothing at all. I'm going to put this on my Masai scrambler 50cc with a 70cc cylinder kit.

Complete piston 39mm 50cc 4T

Good aluminum quality, piston rings are very easy to install and the piston only needs minimal break-in as it already fits very well. Disadvantage: Aluminum is not as durable as a steel piston, but the cylinder is not damaged as much in the event of piston jamming

Graphite piston 65cm3 44mm GY6 4T kpl Moretti

This is a very good product made by one of the best companies on the market in addition it has a graphite coating. The piston is very aesthetically made and packaged when you add the fact that it has a 12-month warranty, the result is an almost perfect product. I rate it 10/10

Perttu

51mm GY6 90cc Piston

Arrived 3pv late and could you please correct the dimensions to be correct as the intention was to fit an 80cc cylinder with a piston and with a trille 90cm³= 80cm³ so I thought a 90cm³ piston is the same size as an 80cm³
