Owner FAQs
- Can I ride the MSX125 Grom on a CBT?
- Yes — the Honda MSX125 Grom is fully CBT-legal in the UK. With L-plates and a valid DL196 you can ride it for two years before progressing to A1, A2, or full A.
- What licence do I need to take L-plates off the MSX125 Grom?
- You need an A1 (17+), A2 (19+) or full A (24+) licence and Module 1 / 2 pass — this 125 itself is restricted to learners.
- Is the MSX125 Grom reliable?
- Honda has a 2 years unlimited mileage warranty on the MSX125 Grom. Launched globally in 2013, redesigned in 2021.
- What is the real-world range?
- Claimed economy is 166 mpg and the tank is 5.6 litres, giving a theoretical range of 205 miles. Real-world budget around 80% of that.
- What insurance group is the MSX125 Grom?
- Group 9. As a rough guide, a 25-year-old in zone 2 London with no claims pays around £465 per year third-party fire & theft.
- Is the MSX125 Grom good for delivery / courier work?
- It's possible, but a scooter like the PCX 125 or SH125i is the standard courier choice. Manual gearboxes slow down stop-start delivery work.
