Pimp my moped!

[WherEmEweeD]

Just bought a wee Peugeot Sum up 125cc 4t clean looking scooter atm.

Was just wondering if anybody new the best options for me to make her a bit more racey.

Previous owner had just had a whole pile of stuff serviced on it and clean it up well.

Im not interested in stuff that wont increase speed or acceleration i have done a little digging about for cylinder kits etc but just not sure whats the best options.

Cheers

sell it and buy a "performance scooter".

my ex had a runner 125 and was pretty nippy, then she went to a 180 and that thing shifted along quite nicely (had indicated 96 at one point)

Big bore kit, jet to suit the bbk, mess about with different clutch springs & roller weight setups. If the Sum Up is the normal pug, rebadged Chinese gy6 type thing then there is a 150cc kit out there.

It is a 125 scooter. Live with it. Horses for courses and all that.

If you look on YouTube, you will find several videos on de-restricting this type of engine, but the problem with that, is that you will be putting more pressure on other components - forcing them to operate outside of their design limits.

You could also make the machine illegal for road use, dangerous to ride, un-insureable, and difficult to sell.

Cheers, gonna read over them and do some research and take a look at the scooter closely this weekend.

atm i'm thinking bbk 150cc (unless there are bigger ones)
new filter
racing clutch springs
sports pipe on it
bigger carb and increase airflow for bbk

any other suggestions or anything i should know about the following mods like best parts to buy or tips on maximising the potential of them.

Is there much point replacing rollers if they seem to be working fine?

You could have a lot of fun with a 9" grinder, purely on a weight saving basis if you see what I mean.

Easiet way of getting more performance pass your test. Also in the long run the cheapest.
De restricting a 125 on a CBT is pointless and expensive.
It's not just about the engine but components such as brakes, suspension etc would need to be upgraded as well.
Also as others have said it could well become uninsurable as insurance companies are not keen on modified bikes as a general rule.
If you are on a CBT its not just limited in respect to bhp but also power to weight ratio as well.
So pass a test ( if you've not already done so) and buy a bike/scooter that fits your needs better.

Unfourtunately as tuning projects go it's a waste of time.

Buget around £300-500 to gain around 5mph and a tiny bit of acceleration.

If you want a quick scoot, sell the 125 & buy a 50cc two stroke...there's off the shelf cylinders good for 20hp availible for those.

Pissing about with scooters is a massive amount of fun - Ignore the "Buy another bike" mob

Well people i'm sorry to say but the nsr 125 is gone i'm just back from NZ working for a year and the mother decided she would sell it to pay some of my debts i left which i never intended to pay lol

I have cursed many times in my sleep about this as I only had about a month of winter riding before i left and secured her up in the back of the garage. i called her the aprilia smoker

Now im at square one scraping away and trying to get myself a better bike I ride 11 miles too and from work on a straight dual carriageway it seems like this bike feels every little slight uphill gradient in the road would the uphill struggles improve with a bigger bore kit?

i'm not to found of the 50cc 2 stroke idea lol I would be happy to engine replacement ideas though.

i don't think the clutch has been replaced in all its 20k miles would a racing clutch make it respond to take off throttle faster?

Just noticed from the journey home the crankshaft seal must have broken as there is a leak. so that will be something i will have to fix this Friday.

Just have to pass the theory then go for the test my instructor says it will be a doddle from putting me through the same stuff as you would do in the test in my a2 CBT on a 500cc honda which was super fun.

Any body tell me how they thought their bike theory was i'm not to fussed about wasting my money on failures. done it once on my car theory that was 5 years ago so i really dont wanna fail this one.
