This style of bike, although niche, has been popular since the sport emerged in the 80s and, though true off-road Supermoto’s are available for competition use, their unique offerings have been utilised by manufacturers who are creating road-legal models.  

In this blog, we are going to look at a selection of the best 125cc Supermoto-styled bikes currently available in the UK!

Rieju Marathon 125 SM Pro

With classic Supermoto styling, including sporty graphics, gold front suspension, and narrow-body, Rieju has got the design bang-on – this is definitely a cool-looking bike that will appeal to the younger audience!

And it’s impressing us on performance too as it’s powered by the same engine found in Yamaha’s WR125, and hits a teenage-friendly 15 bhp so will be easy to handle and control whilst still providing a bit of a thrill.

To maximise comfort levels, Rieju has also included handlebar domino grips, a dual-beam chassis, and a two-way-height-adjustable seat.

At £3,995, it’s the most expensive option on the list today and, when compared against some of the other young-bloods, it’s missing a few key pieces of equipment, like a digital dash for example, but it’s still a decent bike that’s taking riding back-to-basics and is doing it well! 

Price 125cc, 15 bhp, liquid-cooled
Fuel tank 6.3L
Brakes Front and rear disc 
Seat height 870mm
Weight 121kg
Price (starting from) £3,995

Rieju MRT 125 SM AC

Back-to-back, the MRT 125 SM AC is our second offering from Rieju on today’s list.

Through bold graphics, chunky spoked wheels, and motocross-style chassis and seat, its styling is seriously Supermoto and has the look of a bigger bike, which if you ask any teenage rider, is definitely a big selling point!

A few other standout features include the 4-stroke, air-cooled engine which is low maintenance and low on fuel consumption, a hi-tensile steel frame, large 260mm front and 200mm rear disc brakes, and that extremely low weight of 95kg!

Rieju’s MRT 125 SM AC is an all-round machine and even though it’s not the cheapest, compared to a few of the others who are closer to £4k, is still comfortable on the wallet at £2,995.

Aprilia RX 125

Laying at the heart of this updated model is a 4-stroke Italian liquid-cooled engine that is set to deliver a maximum performance of 14.8 bhp. The normal Supermoto upright seating position offers great visibility and spoked wheels are there to deal with tougher terrain; it’ll be easy to bring track to the street (and vice versa) with this good-looking road-legal package.

BOSCH ABS (front wheel-only) with an anti-rollover mode and wide handlebars instil safe, confident, and efficient road handling. These types of bikes have a versatile, forgiving, and tough spirit and are bred to be dropped, brushed off, and picked straight back up again.

As one of the most powerful, it’s a great option for those sporty new riders looking for something with a bit of bite that’s sure to handle fantastically from the get-go.

Whilst Supermoto’s are also known for being relatively cheap, expect to pay a more premium price of £3,850 for this top-spec machine.

Engine 124.2cc, 14.8 bhp, liquid-cooled
Fuel tank 7L
Brakes Front and rear disc
Seat height 880mm
Weight 134kg (wet)
Price (starting from) £3,850

Aprilia SX 125

With a strong reputation like Aprilia’s, and to keep ahead of the pack, the SX 125 needed to be fun and versatile enough to appeal to younger riders who might not have the budget to splurge on a single-purpose bike.

We at BikeMatters think they’ve definitely hit the nail on the head!

Revamped to feature a now EU5-compliant engine, the SX puts out a spritely 14.7 hp and offers a responsive ride on or off-road. Its sibling, the RX 125, only bests that by 0.1 hp coming in at 14.8, so, we know these two aren’t messing around when it comes to performance!

With ‘step into the world of Motard’ as their marketing campaign, Aprilia needed to incorporate the same characteristics that have inspired this model and kept this category alive for so long. Therefore, expect to see BOSCH ABS with anti-roll-over for control, 17” wide, sports tyres for maximum grip, upright seating position for better visibility, and narrow, lightweight frame for inner-city manoeuvrability and sleek body to be easy on the eyes.

Sharing the same technical base and price but differing slightly in capability, both Aprilia models featured are very distinct and high-performance entry-level machines with great designs that will put a smile on the faces of those off-road enthusiasts! 

Engine 124.2cc, 14.7 hp, liquid-cooled
Fuel tank 7L
Brakes Front and rear disc
Seat height 880mm

Sinnis Apache SM

Sinnis’s latest edition, the Apache SM, utilises the basic Supermoto recipe of 17” wheels, inverted suspension, and big brakes to successfully create an agile machine that was born to eat up tracks, trails, and towns.

A fuller riding position allows you to confidently command the road and, as an added extra, a derived Suzuki GS125 engine elevates the thrill of the ride and rewards you with reliability, power, and performance.

The Apache SM is packed full of that raw fist-pumping attitude, so feel the rush as you twist the throttle and hit the open road!

And if you want to spruce your model up more, further modifications are available at an additional cost including a full Toro exhaust with tail tidy and a luggage rack.

Engine 125cc, 11.5 bhp, air-cooled
Fuel tank 10.6L
Brakes Front and rear disc
Seat height 870mm
Weight 134kg
Price (starting from) £2,299 (+OTR)

Sinnis Apache SMR

We’ve only just heard from Sinnis but here they are again, on the list for a second time, offering yet another little throw around in the form of the Apache SMR.

Keeping in line with the traditional Supermoto credentials, the SMR features an upright riding position, an overall weight of 129kg, and ‘fatbar’ handlebars.

Sinnis market this bike as one for the trails so, the frame has been carefully designed to keep airflow tight, distribute the weight, offer solidity and support, whilst also protecting that Suzuki GS125 engine.  

Though these two models may share a name and look vaguely similar, they do differ when it comes down to the nitty-gritty details, with the SMR being the more premium of the two and resulting in a higher price of £2,499 (+OTR). 

Engine 125cc, 11.5 bhp, air-cooled
Fuel tank 7.2L
Brakes Front and rear disc
Seat height 860mm
Weight 129kg
Price (starting from) £2,499 (+OTR)

Keeway TX 125

Keeway’s TX 125 provides the perfect synergy between stability, usability, and excitement.

A typical upright seating position, sticky street tyres and powerful SOHC four-stroke engine blend the best characteristics of dual-sport motorcycling into one fun, sporty and practical two-wheeler.

The fairing is sleek, yet robust, and sturdy telescopic suspension lets you feel in full control and absorb all bumps, jumps, twists, and turns effortlessly. With an 11.2L fuel tank, you’ll have the capacity to cover plenty of miles without having to keep refilling.

Race-spec disc brakes, lightweight cast-alloy wheels, and tons of cornering clearance allow you to make the most of this dual-purpose bike’s easy handling and manoeuvrability.

We didn’t think it could get any better, but a low-price tag of £2,149 (+OTR) makes this bargain!

Engine  124.8cc, 11 hp, air-cooled

The last stop

True, it can be said that these bikes are part of a very niche market, but because of their hybrid nature they’re dynamic enough for any rider, and if this list has shown you anything, it’s that you don’t need a big bike to have an adventure!
