The 2014-2019 Yamaha MT-125 is the learner licence-friendly baby of a burgeoning model family. Designed to be the entry point for new riders before they move on to the A2 world of the Yamaha MT-03 and beyond. It was replaced by the 2020 Yamaha MT-125.

The MT-125 has everything you need at the 14.7bhp restricted licence point in your riding. First and foremost, it looks fantastic. Its beefy stature (for a 125) and aggressive road stance make it look like a bigger bike than it is. Underneath it’s a naked version of the popular and racy 2008-2018 YZF-R125.

In a move aimed at attracting younger riders, Yamaha also included a three-section digital dash which displays a clock, petrol gauge, trip time, mpg, distance to service and average speed.

It’s not just for new riders, though. A claimed mpg figure of 134 makes it a very attractive option for beating the traffic jams on your commute. It’ll even cope with motorway speeds relatively well.

The MT package works perfectly. At 138kg it’s light enough to dodge between cars and get away with it. The 125 gets a sturdy 41mm KYB inverted fork and an improved rear monoshock, the springs are firm enough when piling on the gas and whacking in and out of tight corners and soft enough to soak up road imperfections. The 292mm front disc with a radialmounted caliper offers a strong, progressive bite, especially for a 125.

Yamaha says that the ergonomics give a sporty but relatively upright riding position, and certainly a more relaxed perch for the rider than the sportier YZF-R. While the engine and main chassis components are shared with the YZF-R, the MT features a new tank, seat and footrests to allow for a more upright riding position. The rider is positioned 42mm further forward, while seat height is reduced by 5mm to 820mm.

Tapered handlebars with large aluminium clamps also contribute towards the new street-focused ergonomics, being 100m higher and 35mm further back than the YZF-R125’s clip-ons.

The 15bhp motor packs a decent punch and begs to be screamed. Yamaha has thoughtfully included a shift light to aid those with eager throttle hands and nice touches like that add to the MT’s bragging rights. Get onto the motorway for a mini commute and the baby Yam sits poised and stable at 85mph. Yamaha reckons it will return 134mpg, which means 340 miles between fillups thanks to an 11% efficiency increase over last year’s model.

The liquid-cooled Minarelli engine has been used in the YZF-R125 since 2008 and has proved reliable in that time. The baby MT is put together incredibly well so problems should be minimal.

Our Yamaha MT-125 owners’ reviews show a mainly problem-free experience, but the list price has caused some raised eyebrows in the past.

The MT-125 is essentially a naked version of Yamaha’s YZF-R125 except with an upright riding position and street fighter design, taking its styling cues from its MT-09 and 07 siblings. So we have an already great bike, peppered with upgraded components, for less money than the faired version… and naked. Who wouldn’t want that?

4 out of 5
The MT gets a sharp LED headlight, beefed up by (fake) air intakes either side and a slick three-section digital dash with a host Oil capacity 1.20 litres (1.27 US quarts) BR>?
