You can't it's a 4 stroke, get a bigger bike!

Seriously you can't other than spending a load of cash to turn it into (I think) a 180cc (new barrel, piston etc & new carb), waste of time (and money)
If your resticted to 125cc (as I am and I'm 44!) get a 2 stroke, pull the washers out of the exhaust and go screaming round like a tw*t!

tHE MZ 125 a great bike with a modern engine(i've got a melon Yellow SX) I've even used one off-road but way to heavy and underpowered but a way cool street bike and jeez it'll do 65MPH.

Whaderyerwant?

Comments please?..............................

check the number of teeth on the front sprocket
i think 16 is stock a 14 or 15 will give it more in the dirt
but will kill it for top speed
there are some Yamaha's that have the same sprocket center hole
but no 16 tooth sprocket just 13 14 15 think the old ya6 was one about 1966
and some of the recent yz85 dirt bikes at least in the usa
the prices on hop up parts from Germany stink

I love mine too and is a great bike to commute on, looks cool, good on fuel but it is NOT an 'Off Road' bike. I'm not sure on your use over there as 'Off Road' over here is rocky, muddy and wet, you fall off a lot and picking this bike up at 130Kg's is hard work!

Keep the bike for looking cool and get a ratty 2 stroke for any other fun.

David is right on the prices for German parts as they are very expensive and your going to spend £1000 to get the bike to go 15km faster! Why bother?

Dirt Drift? Yup sounds like you need a 2 Stroke Mate.

Oh and bigger bikes do not cost more, just get an older one!

Mz's don't hold there price well over here and you can get a 5 year old bike in good condition with low miles for less than a third of the price of a new one. 125's because of the UK law after aftificially expensive. If I took my test and could ride a bigger bike (250 or 400) I'd still spend the same money (£800-1k) as that's my limit!

Dear Jeremy,..

:-D I believe the reason the JB or Singapore do not wanna tune ur bike is b'cos purchasing it's aftermarket parts fr.Germany directly is very costly,...just compare the forex exchange,...for them in Germany,...these parts were not expansif.....in

Wht Stretchy elaborate is correct afterall,as d $$ & time spend doesn't worth,...perhap u will just gwe an extra 2bhp+another 10 to 15 kph extra...
The fun of using MZ125SM is that u can get away in the traffic (provided your bike is manage to slot in those narrow lanes),
