Overall Rating 3 out of 5

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 with the R version - but poor build quality and bad handling can’t be ignored.

Ride Quality & Brakes 2 out of 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.

Engine 4 out of 5

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.

Build Quality & Reliability 3 out of 5

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.

Value & Running Costs 3 out of 5

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.

Equipment 4 out of 5

The RS3 comes with a gear indicator as standard and can be gadget-laden with the £400 R kit which comprises of a race-style quick shifter and auto-blipper that blips the revs on downchanges.

Awesome 125!

26 February 2013 by Simon2012uk

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... Read more 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

Rieju RS3

09 October 2011 by Anonymous

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... Read more 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!

Rieju RS3 125

05 October 2011 by urbanbike

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... Read more 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!
