Recently my aprilia Rs 125 blew up, main barings piston job lot even got new clutch because the plates were warped. I want advice on how to run it in because I've seen that you should stick below 5k revs but it's hard to go at that setting off for small gaps etc etc. Any help?

I said it once, and I'll say it again (bring it on, karma nazi's! Twisted Evil)...

Don't bother, it's a shitty little 2 stroke ffs.

Sell it now before it blows up again and let some other schmuck worry about it.

and I'll give the same advice as I did in the other thread...
(but modified due to the extra info provided)


Mine has the same engine (Rotax 122).
All I did was to vary the revs up to 6k for the first 100 miles then gradually increase them after that. It's done 700 miles and hasn't blown up Wink

As it was a full rebuild then you'll need to change the gearbox oil after about 200 miles.


//edited to add :
Your sig says it's a full power RS125
If you're still on L's then you're riding illegally so be careful Wink

Are you on 33hp?

If so, an RS could have a lot of fun with you on most roads...

Even if you are full power, you weigh significantly more...an RS will out handle the boat you are riding. Wink

OP..

Use cheap non synthetic 2 stroke to run it in.

It will be slow, its only 500 odd miles.

5k for 300 miles, 6k for the next 200 miles, increase revs above this distance until 1000 miles then go ragging.

There is a reason people like the above think they are bad. Because they do not follow running in or general up keep/correct oil.

Tbh Paddy you're probably right.

A single cylinder 2 stroke 125 will easily out-accelerate a 500 twin, I'm not denying that.

What I'm saying is, is that for a dependable bike, a 2 stroke is out of the question.
I've seen one too many mates have their (2 stroke) bike off the road for months because of too much hassle with trying to get it fixed.

My bike is the only way I can get to work each day, so reliability has to be the main priority for me.
I couldn't afford to have my bike off the road for weeks on end.

If 2 strokes are your thing, then fine.
But they aren't any fun, in bit's on the garage floor.

Jus sayin! Wink

Correct ... Have had issues with mine tbf ... Using 125 forum, here, and recommended places has been essential.

Seen plenty of lads end up paying through the nose to get um fixed Quick to get back to work. Shocked And because they had not the time or the resource to go to the few 2t recommended places , they were back a week later caus the 400 quid they paid out, was wasted as rebuilt wrong etc. Thumbs Down

I do love my little toy, but if your going Das route within 2 years, then the dreaded Teflon ybr route is hard to argue against.

Although head vs heart self arguments in life are complex !

On ybr ... Wants 2t ..... Blown up or ignition prob on 2t ... Wants ybr.

Getting owned by supped up pedis, wants neither Very Happy

Cheers paddy, but why would you day use cheap non-synthetic 2 stroke?

You are bedding in metal on metal.

Do you really want to use something that will lube them up with ease. Rather run a tank or 2 of cheap shit mineral stuff to help them bed.

Its what I've heard and employed, I had no issues and my RS once run in saw 100mph indicated a fair few times quite happily.
