On the surface the Rieju does enough to be considered ahead of bikes from more established brands like Honda – with a fast engine and extras like a quickshifter - but poor build quality and bad handling can’t be ignored.

2 out of 5 (2/5)

The race rep appeal conveyed by the upside down forks and racy swingarm doesn’t translate into confidence inspiring handling, with a lack of feel and too much weight over the softly sprung front end. On the brakes and tipping in to corners it always feels like the front is going to tuck.

The liquid-cooled single-cylinder Minarelli four-stroke is identical to the engine used in the Yamaha YZF-R125, with the exception of the Rieju using carbs instead of fuel injection which has enabled the Spaniards to squeeze a little more performance out of the motor. Although it’s a restricted learner legal bike, there's a switch under the tank which flicks the bike into race mode, increasing power by 20% and torque by 25%.

Despite sharing the Yamaha YZF-R125s engine, it doesn’t share the same build quality. Bodywork is flimsy, the gear linkage poor and clunky, cheap looking clocks, a low screen and mirrors that fold back above 60mph all add to the impression that it wouldn’t last as well as competitors from Honda, Yamaha or Aprilia after a year of hard ownership.

Whilst being nearly a thousand pounds cheaper (and slightly faster) than the YZF-R125, the Rieju doesn’t have the quality finish or big bike feel of the Yamaha and is more expensive than the well-built and confidence-inspiring Honda CBR125R.


4 out of 5 (4/5)

The RS3 comes with an Ixil exhaust, race CDI, tail tidy and Showa USD forks - pretty good kit for a 125 that's cheaper than Yamaha's offering. The firm also offer a £450 Pro shift ‘bump and blip’ quickshifter which cuts the ignition as you go both up and down the gears.

So I've had this bike for 2 months now and this is my overall view of it: Cheap (a grand cheaper than a yamaha MT and just as quick), economical to run (getting 150 miles on £8 - full tank and cheap insurance), great fun to ride, looks good, feels like a big bike, but very light and easy to handle and makes a good sound. Only down side is the plastics on it are cheap, but despite that they do look cool. Haven't had it long enough to think about reliability, but with 2 years warranty included in the price of the bike, I'm not worried. On the whole, very happy with my little Spaniard! I have no idea why it is rated so low by the various bike magazines/websites. Plus many seem to think its some Asian ball breaker, when it's basically a Yamaha, with an air carburetor, instead of fuel injection, which is simpler to tune, and therefore potentially makes it quicker. What's not to like about that?

Ride quality & brakes 5 out of 5

Handles very well, good acceleration, whips around the corners and brakes are solid, particularly the rear brake which is excellent.

Engine 5 out of 5

Makes a nice noise, will rev quite high, has good pulling power, and accelerates well when overtaking. It's a Yamaha engine made under license, so it should be reliable and punchy.

Reliability & build quality 3 out of 5

It isn't built like a BMW or Honda, obviously, but its not a Chinese knockoff either. Other than cheap plastics, everything else seems to be good, particularly the Minarelli - Yamaha engine, which sounds and feels robust. Its uses a carburettor instead of the fuel injection on the YZF 125s, which makes it easier to tune and hopefully simpler to repair.

Value vs rivals 5 out of 5

Bought mine brand new for under £3000. So far it has cost me £180 full comp insurance and I get 150 miles on 1 tank of petrol which costs about £8 to fill up. It's first service is due at 500miles, and the dealer I got it from will service it for £35.

Equipment 3 out of 5

There is zero equipment for this brand of bike which is a shame, but some oxford luggage does fit it ok.

Poor build quality leading to endless problems.

Ride quality & brakes 1 out of 5

ride fine feels well around bends as long as you don't touch the front brake as it feels like its going to tuck. Brakes fail in winter and rust stuck.

Engine 5 out of 5

The engine is great punchy for a 125 and can easily pull 18 stone riders up hill to 60mph from a standing start. will cruise at 70 all day. but what do you expect from a Yamaha Lump.

Reliability & build quality 1 out of 5

Bike has seen 1 winter and is suffering from severe corrosion, bike is stored inside overnight and had a cover over it at work over winter months in the day yet most bolts are corroded, had to heat many to get them off, seat lock has broken many times due to poor build quality and Rieju admitted that the fuel sensor (replaced 3 times in 6 month) does not work with UK fuel. The wheel bearings(replaced twice) are of a poor quality. I have not had any bearing issues since replacing all for koyos. The brake callipers suffered badly, took 2 large gentlemen and a torch to free the front caliper after severe rust from a bike that at the time was just 7 months old. Speed sensor has had to be replaced recently as well.

good mpg if you ride economically

Buying experience: I have thrown £3,500 away buying this sorry excuse of a bike, and i have spent around £800 so far in its first years rectifying/replacing poor quality parts

5 out of 5 Awesome 125!

I've had this bike from new for about 6 months now so thought it time i gave my two cents worth. It was bought for my nephew but for reasons i fail to understand he decided he prefered his scooter! Pfft! I passed my test 17 years ago so been through quite a few different bikes in this time and tbh i had intended to sell this bike on....but then i rode it haha. Firstly...this is a proper bike, sounds like a bike should and does what i bike should. Im 6'1 tall and the bike accommodates me fine giving a good comfortable riding position. Some have said the handling is poor with this bike but in all honestly i have found the opposite to be true (infact handles a darn site better than some of the yamaha and honda's ive ridden). Feels nice and light when riding and great fun on the cornering. Not found any problems as yet with build quality, like any new bike keep its servicing up to date and look after it and you wont have a problem. Top speed for me has been 78mph but then again im not a light as the average teenager,im sure they would make the 80 mark. What i really like about this bike is the acceleration, for a 125cc this is really quick of the mark!! I tend to overly look after my bikes,so much so that all the fairing is removed once a month so i can give everything a good clean etc. Now on many many bikes this would seem like a nightmare,but it literally takes me 15mins with an allen key to remove the lot......trust me, if you do your own servicing this is a god send! lol Talking of servicing, being a Spanish bike i thought finding parts would be difficult but theres several Rieju dealerships around now all of which can obtain parts within a matter of days, Urban Bikes (google them) are also fantastic at providing anything Rieju related and i highly recommend them. If i really have to give a negative on this bike, its that it doesnt come with an alarm as standard,coz trust me,i'd wanna nick it! lol Great looking bike, great sounding bike, theres even a malossi 183cc cylinder kit available for when you pass your test ;-) Awesome little bike ;-p

I have had my Rieju from new for 4 months. It's a great little bike to learn to ride on & will pull 70 mph up bluebell hill in chatham in 5th (restricted version). It handles ok & brakes well. Ok the the build quality may not be that of the Yam or Aprillia but its £800 less. You gets what you pays for! Minus points: chain went slack very quickly; handlebars dont have end weights, it needs them; seat removal is awkward and clumsy; can never find the horn. Plus points: Its quick for a 125 four stroke & produces power from low revs; you can ride it like a little race bike, great fun; it looks fantastic, this bike turns heads; its £800 cheaper than a Yam or Aprillia. As for the folding mirrors, I have an allen key that came free with an Ikea flat pack. Send me a S.A.E. and its yours!

Yamaha speed and reliability, fast 50s and 125s have been made and abused in spain since two wheels got engines, mine hits 85 by gps (89 on clock) in most conditions and for on road (never tried on a track) handles great (also easily made full power unlike the Yam or Aprilia)some bolts are not as good quality as my old Aprilia, but at a grand cheaper and faster speed i can live with that!
