Just a few questions 125 bikes.

[Hutchysrs50]

How much is the aprilia rs 125 to tax/mot? my tzr 50 is only £15 a year which is great

What sort of performance would i be getting from a 2008 restricted rs 125? 0 - 60 times, bhp/kw etc..

What are the main problems with these bikes?

If i got one with like 1000 miles on the clock, what could go wrong?

How much do you think they would be roughtly to service?

Do you need a tv licence for a tv in a caravan?

let me know, thanks

Hi

MOT is the same price, as is a tax disk.

Performance, realistically restricted 80~85mph and a 0-60 time of probably about 10 seconds, maybe a bit slower.

Biggest problem is people not changing the rings and them failing. Rings are cheap (~£35 last time), but it is a good few hours labour (gentle afternoons work) and then they need running in.

With 1k on the clocks you should be OK, but have no idea how the previous owner has treated it.

Service cost will depend on which service and which dealer.

Think the TV licence depends on whether it is plugged into the mains or running from a battery .

All the best

Do the 11kw versions come with the powervalve but not "wired up"?

how much are they to tax?

how are they restricted to about 15bhp and not the 33bhp?

Hi

Not sure, but I suspect not. The old 9kW restriction was done by leaving off the power valve, solonoid and fitting a blanking plate. However plenty of grey imports were restricted by just disconnecting the power valve (which probably didn't bring them down to the legal learner limit).

£15 tax a year.

They never made 33hp and never seen Aprilia claiming 33hp for them (they gave up claiming power for 125s before the RS125 came out). Maybe 28~29 for an early one, fair bit less for a later one (smaller carbs and the far worse exhaust to get through the emissions tests).

All the best

Hi

Don't know with the latest ones, but on the slightly older ones.

With the exhaust the problem is not so much a restriction as just it being bunged up with a cat, etc. Probably best to just buy an Arrow exhaust, or similar.

The cdi restriction is just in the midrange. Basically a deliberate flat spot between 4750 and 6000rpm. Probably there to get the bike through noise tests. There are (or at least were) programmable replacement cdi units.

Not sure on the air filter. Thought it was just the Mito that had a different airbox lid on the restricted version but could be wrong.

Suspect derestricting it will not really make it any less reliable. Still has the same large ports to give the rings a hard time.

All the best

Hello mate, you considered a different 125 to a RS?

Honda cbr125 would see you through, and I wreckon you'd get alot more for your money.

Plus you'd be pennies in as they are so damn reliable!

If you want economy then Honda CG125 ftw.

If you want performance, then consider a Cagiva Mito as well as an Aprilia.

ive got an 09 restricted aprilia. i got it new but i've already done over 1000 miles. i didn't take it over 6k revs for the first 600 miles, and did the first service (60 quid i think). gets to sixty quite quick, not alot though. i've got mine to 85 mph so far, i think it had a bit left in it as well.

make sure that the person rid it in properely, and let the engine warm up before riding. i always let it heat up to atleast 1 bar on the oil temp before i hop on.

the cbr is really small compared to the rs, and has less power and struggles up hills. the rs is a great bike to ride and absoloutley love mine. makes you feel like a right little biker

[Josh91]

you sure kickstart?? on the right side of the digital read out. i have a fag when i start it up anyway so that lets it warm up a bit anyway.



and (to post above) i dont think you can do much speed in 1st or second gear

oh, just had a look and it is the water temperature.
and all of these 'ask yourself the question', i'd have no idea about that kind of stuff.
either way, letting it warm up a bit first can't be a bad thing

[Kickstart]

[Josh91]

i still don't thrash it. not till i've been trotting along for quite a while. the petrol thing isn't too much of a bother.

and with the engine wear thing, surely it's only minimal and not half as damaging as hopping on as soon as i start it up

[MarJay]

[Josh91]

i'm not questioning whether advice is correct, it's so i actually fully understand the answer.

and i doubted the water temp because it's my own bike and assumed it was the oil. naive of me, but was a little confused when i was told it was something different.
