Wowzer that looks a lot of FUN!  :)

Verdict: Took the bike for a spin and it is rock steady - but too much I think - tyre values with double the grip like the old 125 ITA had  :(. Big tracks make the ratios feel like the gaps are too big. Feels like a de-tuned 125 rather than a tuned 80. Needs smaller tracks!  However  it is nice to have a small bike that can actually be raced again. and even on big tracks I would get a lot of fun from it  :)

I added it to the new BikeMod pack with all 80/125 paints as they work with it.

Great work. I put a server up with it on Imola as it is great on that track

Hi Napalm
The bike represent a Gp 125 Frame, parts and wheels  whit a 50cc "street" engine moddified to have 80cc.
i want to say...the frame have more grip than standard 125gp becose the 80cc engine have the half power than 125cc gp engine. When you have a 24hp on a standard frame (Honda ns1, Yamaha tzr50, aprilia rs50, derbi gpr50) the feeling whit the bike its more poor (loose the front wheel on all corners, you need a lot feelling for make a good corner`s speed, chattering, poor grip...) than a prototype frame (125gp) whit very special parts (ohlins front forks, aluminium frame, magnesium rims....) and special geometrys for race tracks.
On imola whit the biggest relation on gears...28hp.. a lot up hills....this not the best landscape for this bikes...try the mod on small race tracks and enjoy..... we are always ready for listen all opinions and try to improve the bikes!
See u Napalm and thanks for all!
