r/125cc

A reminder to wear your gear. Was going 35mph cruising and did not even notice the oil or understand cause of my crash until paramedics and police confirmed the small oil spillage later. Could’ve been a lot worse as I was sliding for 25 feet until came to a stop. Had a death wobble for a second (not enough for me to react) and came off my bike. An off duty paramedic helped me with bunch of other generous Scots until an ambulance came 40mins later. I was in the middle of Scottish country road with the worse pain imaginable. I did not care about my bike and have no idea what the damage is and im so glad I put myself first.

DXR jacket, scorpian helmet, Merlin gloves and route one armoured/kevlar jeans saved me from much worse. Had doc martens on and even if I was wearing my alpinestars boots, the doctors told me with the way I fell, no amount of gear could’ve saved my ankle.

I am an ATTGAT rider and will never be otherwise.

Had a bit of a crash on my cbr, just wondering who the go to for new fairings so I can tidy the old girl up again, thanks! Prefer a plain colour if I can with no graphics

After a sh*ty chinese scooter, finally my first brand new (secondhand) ybr 125 custom. I'm so proud of my choice and so excited to enjoy it, it have less than 10.000 km and had only one owner before: A really nice middle-aged biker couple who have changed to a bigger cc.

Any tip, observation or recomendation? I have in mind rutes, solo moto vivac and using it as my everyday vehicle.

Have my full license but love my little bike and at the same time really curious about trying out track riding. Does anyone ride track on a 125? Is it still worth it/fun? Any experiences, info, or advice anyone can share would be appreciated!

Not a bad bike if you like something that looks and feels a bit more classic.
Comfortable little cruiser.
Replaced a few of the plastic parts with metal as they are flimsy especially round the break light.
Overall good fun bike to commute on.

Thankfully it was just a slide, I still slided for 5-7 meters tho. Broke the left side peg and indented the shifter, it's hard to downshift now. I'm fine, I just have the tiniest bit of road rash on my elbow and my knee is hurting a little. The crazy thing is, literally 2 minutes before the crash I was thinking "why do I always wear full gear? it's so hot outside and I don't need all of it" and then I pulled my professional 90 degree lean angle, I got a road rash despite my gear, I don't want to imagine what would have been if I was without it.

Hello from Northern Irelanddd

I know I know it's a Chinese model but come on it does look class.

hi im looking to buy my first 125(mt125) I need help as for what to look for to be able to tell if this is a scam or not any help appreciated🙏

Hello, i just got my first project bike, i have never worked on a bike before but i am optimistic, its a Hoajiang CG150cc Chinese bike, its basically a clone of the Honda CG125. Unfortunately where i live cheap Japanese/European bikes do not exist so i had to go with a chinese bike. I want to modify it to either a Cafe racer style or a Scrambler style. Here are the pictures from when i first got it. Any tips and recommendations are very appreciated.

Hey, so i recently picked up a malaguti xtm125 (literally a aprilia rx125 just not an aprilia) and now after an oil/ spark plug change it no longer starts, is there anybody that has experience working with these piaggio M545M engines, or anybody willing to help?

After my service i started it up, then it died, the last owner mentioned a bad battery, so i tried changing that first.

What i’ve tried to do: try a different battery, put back in the old spark plug, test for spark, test the injector, it still just cranks with no start

Sometimes it catches for a brief second, then dies.

Thanks for any advice.

Hello bikers
It’s my first bike, chinese project sold as Junak M12 125cc in Poland, in UK known as Sinnis Hoodlum 125.
When riding, especially braking with the engine it makes that whining sound (you can clearly hear it in the video). When I pull in the clutch the sound disappears.
Is it to be expected with 125cc bikes or does my bike need additional care?

Hey guys,
I’m riding a 2023 Aprilia SX125 and I’ve already installed:
Arrow exhaust (ESD)

BMC performance air filter

So the bike is already breathing a bit more freely than stock.
With my upcoming oil service, I’m planning to add:
FuelX Pro+

Motul 300V 10W-40

HifloFiltro HF563 oil filter

NGK CR9EIX iridium spark plug

My goal is not chasing horsepower, but improving overall rideability:
smoother throttle response

less hesitation, especially when cold

generally a more “stable” and healthy engine feel

From what I understand, with a freer intake + exhaust setup, the bike might run slightly lean on the stock ECU. That’s why I’m considering the FuelX – mainly to enrich the mixture a bit and make the setup more balanced.
So I’d like to hear your real-world experience:
Does enriching the mixture slightly (via FuelX or similar) actually make a noticeable difference on a 125?

Did your bike feel smoother / stronger in the low-mid range after adding it?

Or is this kind of upgrade overkill for such a small engine?

Appreciate any honest feedback – especially from people who’ve run a similar setup 🙏
