After 6 years of quiet success and several small styling evolutions, with an eye on the next wave of young riders, 21YM saw a new MSX125 hit the streets of Europe with an even cooler direction of travel, and a new name – the MSX125 Grom.


For 23YM two striking new colours are available for Honda’s little machine that continues to brim with big dreams.

Model Overview

21YM’s completely redesigned bodywork gave the MSX125 Grom a new design language: fresh and fun, and also easily removed ready for an owner’s creativity to get to work. The LCD dash was also updated to include a rev-counter and gear position indicator.

Now approaching its tenth year of sales, the Grom’s air-cooled engine maintains usable, real-world performance with a fifth gear to help longer-range riding. And the chassis – tried and tested – continues to offer small-bike dimensions with big-bike suspension, braking and handling qualities.


The 23YM MSX125 Grom will be available in the following colour options:


  • Matt Dim Gray Metallic with unique gold wheels and ‘Big Logo’ graphics **NEW**
  • Splendid Blue **NEW**
  • Gayety Red SE with new black front mudguard
MSX125 GROM - 23YM: €4,999.00
