Aprilia RS 125cc

bought a second hand rs this was a big jump from my sluggish 4stroke ybr, had to have a top end rebuild after 2 and half days, im guessing this is why the previous owner sold it as they knew what was going to happen, luckily i didn't have to pay for it as it was under warrenty. since then i have ridden the bike everyday for the past 6 months with no problems, the only downside is the money that it costs to keep it running, loves to drink petrol other than that can't fault it.

Just bought the above and it loses electrical power under load. Neutral light goes out and misfires when revved. Please help!!!

I purchased a brand new sbk model rs4 125 as a commuter and city run around. I could not be happier with the bike. In the past ive owned various gsxr 750s 1000s and a couple of ktms but I was looking for something for short commutes and running around town on with better economy and running costs. This is a great little bike with big bike feel to it its been ultra reliable and soooo much fun to ride with thequick shifter and being light wieght you can really throw it around and it cruises at 73 with my 13 stone on it so not bad in standard form for a 125 four stroke . Tune up parts are now available in the form of big bore kits boosting it from 15bhp to around 28bhp depending on the kit you buy so srill a gret first bike also and much more reliable and lower maintenance than the old rs125 two stroker. All in a great bike amd would heartily recomnd it have fun and enjoy one :-)

i bought a new rs4 125 in january 2012 from inmoto croydon and its been back to them 7 times in 10 months,i didnt use it for 3 months,and guess what its gone wrong again,they lied to me when they sold it,they said all new bikes are road tested for inspection and are given a good run,mine had 0 miles on the clock so dont how they did that,then a oil leak devoloped they fixed that,then the gears wouldnt change they did that only for it to go wrong again a week later,so it went back again this time they said the clutch needed adjusting when it came back they had left the crank cassing unbolted,so it went back again,then the gears kept getting stuck again this time they said it was the quickshift so they removed it,then it wouldnt go into neutral back again,then stuck in 3rd gear back again and told its had a good run to test 1 mile,now you have to sometimes give the gear lever 2 taps to change gear and its leaking some pink fluid,in my opinion avoid aprilia and avoid inmoto

i have power to my coil and hd lead but its still not sparking ? any ideas ?? please email me at [email protected] thanks

i have just baught an rs 125 i want to rebuild it and tweek it abit what would people advise my email is [email protected]

Bought a restricted 06 model used, firstly for what it is it's a very quick bike. With my 14 stone on it would easily do about 80mph restricted, it's also so light that you can throw it into corners and lean it back fairly easily even if your inexperienced; this is also why it seems so quick.

Reliability wise it's what you'd expect from a GP rep sports bike, after 500 miles on mine the crank oil seal went, which cost 400 pounds for bottom end rebuild as you cannot remove the swingarm locknut to remove the engine without the expensive aprilia tool.

After it was rebuilt 1000 miles later it blew the clutch cover gasket,(tip don't use pattern parts on it, only genuine aprilia or some race spec alternative). This bike had been maintained very well by the previous owner

who had done the top end rebuild at every service interval, but you have to also remember to do the oil seals every 10,000 miles.

After that it ran fine for the next 4000 miles, I derestricted it a while ago which seemed to make the bike go like a rocket, I was chasing down yammy R6s for a while, though they would just leave me after about 60 mph; though seriously the powervalve makes the bike a lot safer and rideable with no compromises with reliability as long as you remember to up-jet after each mod. Also it's only 28hp untill you fit straight through exhaust.

i brought my rs125 in december 2009 its now september 2010 and the list of problems is just getting longer i have bearly been able to ride it as the preveous owners had no idear how to look after the bike and i have spent the best part of 9 months repairing and pumping money into the bike

my problems have included: blown cylinder,faulty coil, faulty cdi, numerouse faults in the ignition system and other electrical systems and they go on

my advice to anyone looking to buy an rs125 is inspect it with a fine toothed comb take the bike for a good test run qwestion the seller on the maintenace they carried out and what ever you do dont buy on that has been tamperd with get it standard if they have been tamperd with you will have nothing but problems and the parts dont come cheap if you buy one and decide to modify it seek proper advice and ensure u can keep up with the maintenance because there will be alot of it and also only use top quality lubricants and oil's

Excellent bike, great fun, keeps up with larger bikes through corners.Would recomend as it is a great step before jumping onto a superbike. Clutch cable has been an issue as I was stupid enough to buy cheap of ebay.Other than that it has never let me down. So long as you keep on top of the oil situation. Use fully synthetic injector as well as engine oil. Requires a Change of engine oil frequently. I use castrol.

very fast for a 125cc very quick at takeing off only broke a few time very good as a learner bike can beat all 1.2 cars
