You cant really tune too much, its only around 11-12hp as standard.
You could adjust your sprockets, get either slightly more end or acceleration.
The only thing that stopped me getting a Megelli was the low amount of power it had, felt very sluggish!
There isnt a power limiter..its just a very slow engine.

Why does everyone lately seem to want to tune low output 125cc 4stroke singles, that have a poor tuning potential? Maybe im being grumpy, but over the last 12months there has been dozens of threads from people asking to de-restrict and tune air cooled 4stroke single cyl learner bikes.

If you buy such a bike often quite cheaply too, as at least 1/2 of them are probably low quality Chinese copys of out dated Jap bikes, then why can't people accept that 10bhp or so is all you have and all your likely to get. If you knowingly buy a bike like this then why on earth would you want to ask idiotic questions about de-restricting or tuning it?

Maybe im being hard on people here, and i suppose that i should accept that there are always new riders and beginners joining BCF who don't have much bike knowledge, but i can't belive how many people keep asking the same old shit about how to tune very basic 125's that if they wanted to go fast they would/should have never brought in the first place!

There is nothing wrong with a 10bhp ride to work Chinese bike, and they are cheap and cheerful but that is all! If you wanted a new 75mph+ 125 then you would have brought a YZF125R or an older even faster 2stroke etc etc.

If people are going to buy the cheapest slowest 125cc bike available, then just don't come on here looking for tuning advice please!

I think that to try to tune and to share expirience with other people is good idea...sometimes people can not by expencive motorcycle so idea to tune and to increase power is not bad ..I have Megelli motard 125 (super moto) almost 2 years and 15000 km on my dash board and I am suttisfy ...it is exelent every day bike ...no big troubles and good quality ...usualy I use it to go on work and to fish almost everywere in Macedonia...
Best regards

look my friends ...I understand that what you trying to tell me..and I know the difference between 2 and 4 stroke..and I understand that the tuning is expansive and I can not increase the power and max speed a lot......thank you anyway...
here is the steps what I done on my Megelli:
--another crankshaft
--cyl+piston 180 cc
--another carb for 200 cc engine
--another clutch assy
--new hand made inox exhaust
Result:much more power and max speed about 120 km/h and I believe that if I change rear sprocket with 37 teeth I will increase the max speed
also I try and made experiment and again change the clutch assy ..where outer clutch have 3 teeth les and front sprocket what is come on the crankshaft with 3 more teeth..
Result :much longer gains ...in 4-th you can cruise with the bike with 105 km/h on 7500-8000 rpm and you can forgot that you have 5th...and in 5-th gear you have max speed about 135 km/h....
Also I have an idea to find a head 4 valve from Honda XL 125 ,and 6 gears shafts from the same engine (I have to find them and check is it possible to put them on the engine) because I think that it will be ok so...we will see...problem is only that it is very hard to find parts here in Macedonia..it is a small country with only 2 milion people population and we are really small market
all this things I made it for my pleasure..and just to try ...
again...thank you a lot for your opinions and I respect it...
and I will inform you again...so take care my friends

180cc pushing 120kmh...again, money spent but power not made!
The bike bashing on here on the YZF r125..ive got that to 130kmh.. ragging the mothers out of it down a hill.
Standard 125cc, You have spent money on a bike that cant really go much faster, but well done for actually wasting hard earned cash Thumbs Up

..that is true my friend..for me is the same..everything on two wheels is good if you enjoy riding it..but it is in our nature to look for more and more...so that is the way of the people's progress...I can not wait anymore for better weather and restricted fishing of rainbow trout...so ..me and my Megelli will have a lot of fun in the mountains

My old TDR125 2stroker used to hit 120kmh/75mph (i think?) without much fuss in standard form...

Only cost me £500 for the bike......then i did some cheap tuning mods (porting, engine rebuild, skimmed head which all together cost less than 50quid) got another 5mph out of it and a bit more torque....

Just to rub it in... Cool
