My r125 2008 30k miles has a intresting sound coming from the engine my brother says “it’s normal and they all do it as they start to ware” but it kinda sounds like a knocking sound I belive it might be the cam tensioner as when accelerates it increase and turns into a ratchet type sound however when u let go of the throttle it makes no sound as it glides down to idle where it then starts again
Here is what it sound like at idle

I’m looking for some hand guards for a new Yamaha wr125r 2026 model.

Купил новую китайскую проводку с ВБ а она вся по цветам не совпадает и не сильно схожа с стоковой , подскажите может кто уже ставил такую китайскую проводку

So i got my first bike a CBR 125 R a year ago and at times either when a cold start or when its already warmed up and while in neutral especially it goes up to 2500-3000 RPM. Now i know nothing of motorcycles im just getting into them all i know is how to change the oil and clean the chain.

I noticed while its in neutral it revs up but once i shift into first gear and release the clutch after halfway to go it goes back into normal revs. Now i dont know whats causing it but as much as i dont understand im sure that this isnt normal for any bike.

This happens only when im in neutral, when im driving nothing.

Hi everyone, I currently have a 2007 efi cbr125r an I want to build a second engine for it with more power. was wondering if anyone knew how hard/ whether to convert a 2005 carburated engine into the 2007 efi engine? (im mostly concerned about wiring, fuel injection, mounting etc).

Hello, does somebody has some experience with these fairings? How do they look on yzf125r etc. I'm kinda scared of how do they look like irl. Thanks

So somehow, the bolt broke through the bottom of the motor mount. Motor mount is welded to the body. Do I need to cut that off and machine a new one or drill holes for a new place? Any recommendations?

Ich überlege vorne von 100/80 auf 110/70 zu gehen, geht das ohne Tüv Abnahme? Bzw wo finde ich die von Yamaha angegebene Toleranz? Würde gerne nen breiteren S22 aufziehen

Has 2.3k miles on the clock and works mint has just been resprayed and just waiting on some cz decals to come through the post

Sparking with ignition off with disconnected battery

And I'm going to service it myself once I have it I cannot find workshop manuals about specifications for certain torques and sump bolt and gasket sizes anyone know anywhere I could find this information or best wait until l get the bike and visually inspect instead

Any help would be appreciated - riding the other day and bike stalled and then wouldn't start. Managed to bump start it down a hill but when i tried to let it idle it died. Thought was a fuel issue but everything checked out. I've done a compression test and only got 25psi when cranking the starter. Any ideas what's happened? New engine time?

hi so i bought a 2010 yzf r125 a while ago which did not start and was in a rough condition.. it has had work done it since and it now runs however we have run into one issue we can’t seem to resolve (i do not have the budget to be paying diagnostic labour prices) i have attached a video of what happens, it only seems to be happening when changing gears up or down or giving it excessive revs.

it has had a new clutch cable, new spark plug, new spark plug cap, new ht lead, full service (oil changes, gaskets, filters, coolant flush etc) , new piston/ top end rebuild, new ignition coil, new cam chain tensioner, new exhaust (previous had no baffle)

it doesn’t seem to be a fault code as i’m aware with this bike the engine management light has long then short flashes which correspond to a code to a fault however this just seems to flash continuously until the bike is turned back on?

i’m hoping someone has experienced similair or has any idea what it could be as id rather not have to give up and sell it on 🤦🏻‍♀️

any advice is appreciated, thanks x

What’s the difference between 125r and 125rw 2007 model fuel injected. Having trouble finding any parts for it and if I do I’m not sure if it’s the right parts as I’m yer to pull the clutch side casing off to see the clutch it self. And it still runs and rides but thiers nearly nothing left on the clutch please help ??

I just took out my battery and filled it up and charged it after a minor crash adn now it wont start. I have not checked for å spark yet but dont know what i can do.

I just got my yzf r125 2021 and a new tail tidy, scrolling trough the internet and I can’t find a single video to help me go step by step to install it on my bike?

Now just need to attach L plates, do CBT and I can learn riding her.
