First Look: Honda MSX125 Grom

Honda brings ‘Grom’ name to the UK, adds fifth gear and fresh styling to uber-cool mini-bike.

Unlike cars, most bikes are known by a jumble of letters and numbers, instead of ‘proper’ names.

Partly that’s down to bikers being more expert than car buyers – you wouldn’t expect a typical shopping car buyer to hanker after a ‘Ford FSRC1400D T’ rather than a Ford Focus 1.4…

But bikes do occasionally get names – sometimes disastrous (Suzuki, we’re looking at your Marauder), sometimes super-cool, like Honda’s FireBlade.

Bizarrely though, the big H didn’t use the FireBlade name in the US and other world markets.

They got the CBR900RR instead, not a bad name, but much less evocative for sure. The firm reversed the situation in 1996 with its awesome Gold Wing-based custom.

It was dubbed the ‘F6C’ in the UK, but known as the Valkyrie in the US – a much more appropriate title for the 1,520cc six-cylinder beast.

Honda did it again with the MSX125 mini bike – we got the dull name while it was called the ‘Grom’ in the US and Japan. (Type Grom into Google Translate btw, and you get ‘Thunder’ in Russian, Ukrainian and a load of Slavic languages, apparently.)

But people soon started to call the MSX125 a ‘Grom’, preferring that cool moniker to the ‘part-number’ MSX125 name. And now Honda has joined in, with a 2021 MSX125 Grom for the UK and the rest of Europe.

There are many more changes apart from a cooler name for the 2021 model…

The changes go much deeper than the cooler, globalised name though.

A new engine has a 2.4mm smaller bore and 5.2mm longer stroke, now 50×63.1mm rather than 52.4×57.9mm, and compression is up from 9.3:1 to 10:1 – while the transmission gets an extra fifth gear.

The motor remains air-cooled for simplicity and low mass, while updated PGM-FI fuel injection helps it meet Euro5 emissions regulations.

Power remains the same, around 10bhp, and fuel consumption is a stonkingly low 65.7km/l – 153mpg (imperial) in old money.

Bigger changes appear elsewhere.

The bodywork has an all-new look, with bright acid colours, and easily-removed panels. Honda says that’s to allow owners to get creative with customisation, although we’d be a bit worried about parking one up in London and coming back to a (totally) naked Grom…

The Honda MSX125 Grom will be available in 3 stunning colours.

The LCD dash is updated with a new rev counter and a gear position indicator (essential with the 25 per cent increase in ratios we guess…), and the fuel capacity is up half a litre to six litres.

The chassis is mostly as you were, with the same steel backbone frame and suspension that promises ‘big bike feel’. The brakes have an IMU-equipped ABS system that’s a cut above the norm in the class and adds extra stability and safety on the brakes.

Finally, UK bikes get a yellow shock spring plus gold-finished forks and brake calipers, for that extra-premium look. Nice.

There’s no official word on price or availability as yet. Keep an eye on for updates later in the year!
