125cc Anyway of improving performance?

[darren01274]

Hi all is there anyway of improving the performance on a 125cc engine

[no_shad]

Send it to Stan Stephens.

[darren01274]

whats that and where is it and what do they do

[Ste]

They do two stroke tuning. www.stanstephens.com If it's a four stroke 125 then forget it.

I'd say to save the money and put it towards buying a bigger bike once you've passed your test.

riding down hills improves performance
you accelerate quicker and have a faster top speed

also 'racing' exhaust and 'racing' filter help a bit but not as much as a big hill

Stan stevens is pretty much for racers.

Although it sounds boring. The best thing you can do is save your money for a bigger bike.

There's no replacement for displacement.

Hi Darren,


I had a gilera runner sp 125 did about 75 standard then i got a bore kit 172cc & it did just under 90mph.

Front end will lift when you accelerate. It was £250 fitted. I have no complaints about it, I rekon it's the best way to mod a 125 without changine exhaust & other parts.


Thanks.

That was back in my ped days I still think tho it's a great piece to have on a bike. Only trying to help with his question

well what kind of bike do you have? if its a 2 stroke restricted 125 then it probably wouldnt be too big a problem to de-restrict it. (though this would of course make it "illegal" to ride on a provisional with L plates) with a lot of 2 strokes there loads more that can be done. If its a 4 stroke however then there is a lot less than can be cost effectively done. If you post what kind of bike you have i think a more accurate answer could be given.

How to modify a 125cc engine EG make it quicker.

Adding a 175cc bore kit would make it no longer a 125cc so you would therefore be modifying a 175cc engine bike not a 125, sorry about the post i just have a thing about bore kit's.
