The Cost of Running an Aprilia RS 125 (2 stroke)

[@sire5582]

Get the bridge cut in the ECU. Remove the soft rubber on the underside of your ECU til you see the circuit bridge and cut it either side creating a gap so it's not connected in anyway. Replace with new silicone rubber ; ) . I had a few RS's as a lad and that was the 1st thing I did when I got one. De-restricts the engine giving you the full 33hp on the older models which you have. Optionally but highly recommended remove your airbox and replace with a cold air intake (custom a K&N air filter onto it) adjust your carb for the extra air intake as you go or use a dyno, this will add a further 1-2hp. It's the difference between night and day on these little pocket rockets. They become absolutely rapid. You're welcome.

[@Tiwey]

Hell yea, you know the thrill. I also modified the cdi

[@att49356]

CDI mod is correct. But I'd keep the original airbox since the cold air intake gets from the front anyway. Adding an air filter like you say is just going to cause constant carburation adjustments at any time weather changes. 34-36mm carburator and a PVL or Selettra (125 model) will do much better than such filter mod. With a PVL or Selettra you get your wiring loom cutted out of power, all you have to do is just rewire it so it gets power from the battery, and you can simply make a connector for the battery so you can recharge it any time you need. These mods will give you all you need to enjoy a 125. Avoid 160cc Polini cylinder kit. You get better results by simply cleaning fusion refuses from the original rotax cylinder and with a good cylinder head. You can also have a different squish with stock head, if needed. Don't mess too much with the compression ratio or you could damage your engine. Get a good reed valve, such as the V-Force3 by Moto Tassinari. This way the bike will be efficient, reliable and will give you less headaches.

Ive had a 2t moped for a while now after fixing som minor things and cleaning the carburretor it was fine.

[@JamesTheBiker]

Great little running costs review buddy! love the comparisons between the RS 50 and RS 125 ;) I remember my Rieju MRT 50 SM Pro that was 2 stroke and the main problems I was having was the spark plug messing up. My fuel was running rich and I had to keep cleaning the spark plugs but overall 2 strokes are fun little bikes and brilliant for beginner riders ;)

[@RossRS]

They are a lot more fun to ride than 4 strokes! However my next bigger bike will probably be a 4 stroke (for the reliability)

[@JamesTheBiker]

Yep I agree there buddy and yh it's a lot easier to maintain with a 4 stroke as well 😉

[@Joel_Nilsson]

@@RossRS There are no bigger 2-strokes on the market because of the damn emission regulations. So the only options are 4-strokes. The reliability of 2-strokes aren't bad they are just different because a 2-stroke might get minor issues every now and then but they are easy to fix and even if there are bigger problems they shouldn't be too difficult to fix. If anything happens to a 4-stroke of to the workshop pros it goes at least if it's somewhat bigger than an oil change

[@BenEyah]

I have to disagree with the unreliable 2 stroke bit, I had a 10 plate rs 125 and the only times it gave up was down to whoever was riding it, it was always kept outside uncovered and no matter what the weather it started almost straight away unless it was left a few days unused then it took about 10 seconds to get going. Friends abused it (even though I asked them not to) thrashed it when it was cold, slipped the clutch like there was no tomorrow and I changed the piston n clutch around 11k miles and it had at least another 10k worth in them both and that was all that got changed along with a clutch cable which snapped from rubbing on the sheath. I had a cr85 as well which never missed a beat until somebody emptied the radiator n didn't fill it up so melted the rings on it overtaking a car and that was the same started first time everything but as long as you sorta look after them they shouldn't just give up

[@CAFCHardman]

Bennie Bounce same here they are really very reliable. My 2 stroke full power 54 plate RS did about 7,000 miles before needing a new top end (going to be ready for summer hopefully)

[@jamesdean3980]

Hardman 190 needing to replace a top end at 7000 miles is not reliable even for a two stroke

[@derf9465]

It's every 6000 miles for the RS250. When it makes 240bhp per litre it's highly strung in road form. But when an engine this small develops that much bhp. On 1980's technology. Things will wear, they rev harder than 4t, don't have fancy oil suppression rings or holes in the Pistons, fire everyother stroke generating lots of heat. Nope it's not going to last compared to a heavy 4t. That may last 30000 miles but cost up a rebuild on a sports bike even if you do the work yourself and it's £1000's.

[@will5459577]

This may sound like a dumb question, but how would you downshift? What I mean is, would rev matching like on a 4 stroke work? or would it be better to just brake and shift whilst holding the clutch?

[@RossRS]

You downshift in the same way. I would downshift then hold the clutch in to avoid engine braking.

[@bve7397]

Overall if you have to buy a cylinder kit and do a rebuild sometimes its totaly worth it! I mean its way faster than a 4t 125, and since i Will be limited to a 125 I rather spend more money and have some fun

[@harrisonjefferies8151]

I am getting a RS 50 1998 model, is the oil the same as a speed flight 2 as was driving one of them before it broke. also i have been told that you need to mix the oil and fuel in the fuel tank, can any one tell me if this is true or is there a separate tank on the 1998 model. also great video.

[@RossRS]

The speedfight would most likely use different oil as the RS is geared with a clutch whereas the SF is auto. It depends on the bike as some people remove their 2stroke oil tank so it's best to check. Normally it should all be connected but it's best to ask the previous owner.

[@malinjones6815]

I’ve got a rs a bit like that but a bit older I can’t seem to get it to start it’s getting fuel and has good spark but just won’t fire up any advise

[@RossRS]

Red the Hero The bike requires more attention than 4 strokes (generally) however, the performance and fun factor is next level. I'd recommend getting one if you're mechanically minded and are happy to work on your bike. I have not had many major issues with the RS and it has been reliable for me but every bike is differentand it depends on how it's maintained

[@TremourSphereUK]

I remember it cost alot in 2 stroke oil and little bits and bobs like throttle cables and shit, cool bikes though, ever thought about doing your a1?

[@RossRS]

Oil is definitley an ongoing cost. You've just got to be prepared for things to break and to be replaced. I've thought about doing it however, my bike isn't ideal due to the turning circle and also it might be a bit too quick as they check the bikes over.

[@FalconFear]

What would u suggest to increase the speed or power on the bike? Mine struggles to keep increasing its speed after 60mph before i could go to 90's

[@RossRS]

Most 2 strokes have seperate oil tanks so you just need to make sure they're topped up. Premix is fairly straight forwards todo, you just need to calculate the amount of oil to get the ratio correct.

Do you guys think its worth it to buy a 50cc bike at 16 like the rs 50 or wait until 17. I think the rs 50 would be sick but with a restrictor is it even worth it to go only 30mph? And is it possible to go without one (I know its illegal)? How much does a restrictor cost to fit ?

[@RossRS]

The Rs 50 is a great bike, if you can afford it I'd go for one then when you're 17 sell it and then upgrade. I've never seen a 'restricted' rs50 so I guess they are very easy to derestrict if you do find one. Without any restrictions my bike could do about 55/60mph tops.

There cheaper than 4t. If you price up engine work. 2t are really simple, most simple mechanics, can rebuild these with simple tools. Any engine is unreliable if you treat it poorly. I've owed 2t for years from a H1 500 through the rd250 to RS250 with Rxs100 and Gp100 inbetween and guess what all reliable. Some used as daily commuters other for fun. It comes down to the mechanical understanding of the owner. Listen to a lot of riders many can't change a chain without a dealer. I've rebuilt countless engines and seen the damaged caused by idiots who just rag them. Yep engine work comes around sooner on these things. If you get the chance have a look at the internals on a 4t just as bad as many owners just destroy them in kind.
