My 18yr old god-daughter has been riding since she was about 8. She is tall and thin so we needed a light weight enduro bike. She rides well, her riding style is probably better suited for a 4 stroke but 4 stroke size and weight do not leave us many options.
We had a GG EC125 that my son's rode in some enduros and it was a very nice bike with a nice large power band including good low end power. Based on our experience with the EC125, we found and bought her the GG MC125. Unfortunately, the MC125 turned out to be a typical 125MX bike. The MC125 has very limited low rpm power especially in high altitude technical riding, making it a challenge for her to ride.
On a side note, we have a GG MC250 engine in my son's EC250 and it has good low rpm power similar to the EC250 and it rips in high rpm. I am pretty certain the MC125 issues were tied to the lighter flywheel, Messico pipe and MX porting / port timing. As expected the MC125 has a strong mid range and top end power but that is not the way she rides. I have way too many hours invested into finding low rpm power in the MC and while it is much better than it was, it is still a MX125 a it does not suit her riding style.
When I bought back the GG EC125 from the guy that blew it up and found that it needed a full rebuild, I decided a 144cc big bore with the heavier flywheel and FMF pipe would be a great way to finally resolve the low rpm issue for my god-daughter.
At this point we need to swap over the EC 144 engine ignition and pipe to her MC125 and then I will build up and sell off the GG MC125.
