Hi there, I am looking to buy an RS125. I've just got my CBT.

What is the rough price of a decent one? The ones I've seen that look good are priced between 1100-1500.

Also, what's the average 0-60 on the bike, and how much will it cost to get it de-restricted.

Many thanks, Paul.

Hi I've had my RS 125 for 7 months now, and it's absolutely fab. I paid 1600 pounds for it, it is a 2004 plate, and it's slightly modified. It does 0 to 60 on average in 6.5 seconds, and mine does 90 mph at the moment. I would highly recommend one of these any day of the week. Ps put a micron can on it; it sounds great.

I've got an RS125 on a 2000 plate. The only bad thing I can say about it is the speedo cable and not having a petrol light! Mine's done 10,000 miles and it still runs like a dream. It's my first bike and I love it, it makes me happy to get up in the mourning knowing that I'm gonna ride it. And mine's hit 120mph!!! Amazing bike, defo buy one, you won't be disappointed.

I have a full power 2001 RS125. Bought it April this year with only 544km on it. Had it 6 months, and apart from a clogged up carb due to being stood for ages, it has not missed a beat. I run it on shell VPower and Motul 710, and ALWAYS warm it up. Plus I take it easy for a few miles, and as yet had no problems.

Best I have done is 90mph, but I would not describe myself as aerodynamic.

Hi, some interesting comments there! Here it is from my point of view. I have just bought a brand new 08 full power RS 125.

I agree, these need to warmed properly, although try to hammer it before it's warm, you can`t, it'll restrict itself to 4000/4500 rpm. Must be a safety measure.

As for breaking in gently, mines got a sticker on the tank that says "keep under 6000 rpm for first 1000km" bulls**t! Mines got 600km on it now and since about 500km when I took it for its first service, you can open it out. Not all the time mind, this would blow any engine, but it doesn't harm to blow the crap through once in a while.

Just enjoy it! It's a 2 stroke racer, it does what it says on the tin!

Hi all.

I have got myself a 2005 RS125, had it about a month, did have 350Km on the clock, now has 850km.

Been keeping my revs between 7 and 8000, bit difficult when driving on the A2, but have gone up to 9000 but only for a second or two.

Do you think I'm pushing it a bit much? I always warm her up to 50/60 before setting off. And wait till the temp gets to about 65/70 before hitting 8000...

My main concern with her is the clutch.

I'm not sure if it's how I pull away, as I used to have an NSR125 and its first gear is very different. Can anyone tell me how you are supposed to pull away without thrashing it? I get the impression the bike wants me to do one thing, but as it's not fully broken in yet, I'm being told to do another...

But, I will for the second time tonight have to adjust the clutch at the box as it becomes loose! The lever gradually gets looser and looser until I have trouble changing gear! The tool kit that comes with it has the tool specifically for adjusting the clutch, making me think that this is to be expected...?

Anybody else had this problem or know what may be causing it? My pulling away and traffic filtering clutch control possibly? Is stopping and starting in traffic going to do this to it every week?

Any advice would be appreciated.

Well I'm sitting my CBT on Saturday, and I've just been out and bought myself a 2001 RS 125 Chesterfield replica with 2136 miles on the clock. She looks like she has been looked after really well, and I can't wait to get on her.

I'm a late starter on the bike scene, as I'm now 30 and have never been on a bike since I was 15 (I think I can remember that far back). I feel like a big kid at the minute as I'm so excited to get on my RS, it's like Christmas.

Thanks for all the helpful hints.

Hi, recently bought a 2005 Rs125 for my girlfriend to learn on, no service history, but a great looking bike. Seemed to go OK, but not as fast as a 1986 Suzuki RG125 I used to have, so I immediately ordered a gasket kit, as the bike had no service history with it. I started using it for work, as my 950 KTM had a regulator problem, and that was on order. Brilliant little bike and great fun, taking me back to my youth of screaming the nuts off a two stroke!

However, after about a week and a half's use, the engine just packed up. I took the top end off, and there were loads of small metallic objects embedded in the piston, and the cylinder head and bore are also pitted. Now I may have to rebuild the entire engine due to iron fillings and premature wear.

In short, don't try to guess whether the bike is OK for a few more miles, get it serviced and enjoy, and if in doubt, remember it's not a 950! LOL.

Yeah, great fun those little strokers. Started years ago on an RG80, then got a TZR125 and a year later an RGV250, all on a provisional licence with fully comp insurance on the RGV250 for £200 as well. Ah, those were the days.

Sold my RGV in late 1998 after 5 years of use to and from work (20 miles each way). Never gave me a moment's bother.

You have to look after 2-strokes engines very carefully. Top quality, fully synthetic oil and careful warming up are key to longevity. The temperature should be around 50-55C before driving away, and then keep it under 7000 rpm for a few miles before letting loose.

The Japanese 2-strokes were well known for being more reliable than their Italian cousins (Aprillia, Cagiva etc). The reason was the Italian bikes were more highly tuned, producing more power, hence less reliable. Any 2-stroke will never be as reliable as a 4-stroke, but a 4-stroke will never be as exciting as a 2-stroke.

In 2006 I picked up an RGV250 again. A lot of work and cash was needed to get it back to reliable working order. Since then I've picked up two Honda NSR250's, an MC21 and MC28 as well.

Such a pity they don't make these anymore.

Aprilia RS 125... It's a 2 stroke... What do you expect? Try running a motorcross if you think it's a unreliable bike! They're typically Italian. Little and highly strung. Full power (33bhp) is mental... Handles, accelerates and stops perfectly.

Mate, my RS is red hot. De-restricted she is awesome. Look after her and she will gladly look after you. One of the best bikes I ever rode...
