"Supermoto is powered by the same engine you'll find in Yamaha's YZF-R125 and WR125 range"

Overall Rating 4 out of 5

Rieju’s new Marathon 125 supermoto is powered by the same engine you’ll find in Yamaha’s YZF-R125 and WR125 range, albeit fitted with a 30mm Keihin carb instead of fuel injection. Costing £3199 this Spanish-made machine is actually £400 cheaper than Yamaha’s own WR125X supermoto.

Ride Quality & Brakes 3 out of 5

The seat is unbelievably hard, but on the move it’s light and flickable and it’s a lot of fun. It’s softer than its hardcore looks would suggest and the suspension is on the bouncy side. The brakes lack bite too.

Engine 4 out of 5

Powered by a liquid-cooled 125cc four-stroke engine, it has a learner-friendly 15bhp in standard trim, but is available in full-power (20bhp) if you have a full licence. Flat-out, head down, it does 73mph.     

Build Quality & Reliability 4 out of 5

Rieju may sound like a dodgy Chinese brand but this is a quality piece of kit, the engine is well finished, the styling bang-on and the quality of standard components high. There are a few cheap and cheerful bits that aren’t quite up to Yamaha standard, like the side stand, which flicks up as soon as you stand the bike up and the tacked-on starter button fitted to the left side of the handlebars. But overall the Rieju is an impressive package. You can also get the Marathon 125 Pro Enduro, which is exactly the same machine, but with bigger wheels and knobbly tyres for exactly the same price.

Insurance, running costs & value 4 out of 5

Three grand is a lot to pay for a 125, but it’s the going rate for these funky learner machines. Honda’s uber-successful £3070 and Yamaha’s own £3699 YZF-R125 continue to sell by the bucket-load, and proves there’s a big market for funky 125s, so there’s no reason why the superb Marathon 125 Pro Supermoto doesn’t deserve a slice of it.

Equipment 4 out of 5

The Rieju comes with a high level of standard equipment, like 40mm upside down Marzocchi forks, a wavy Galfer front brake disc, braided steel brake lines, an aluminium swingarm, Domino handlebar grips and a two-way height-adjustable seat. Weighing in wet at just 117kg, it’s a massive 20kg less than the Yamaha WR125X. Compare and buy parts for the Rieju in the MCN Shop.

the sound

27 May 2011 by kennon

as with the title the noise of this bike is phenominal, the ride is okay be it like sitting on a wooden plank, only downside is not having a warning when your low on fuel or a fuel guage as iv found out already coming up on the side of the road... Read more waiting for a jerry can to arrive. cant be going flat out yet as im running her in atm but the Yamaha/minarelli engine is a real peach to work with amazingly good fueling for a carb even in heavy traffic
