Metzeler Roadtec 01 Scooter 120/70 R15 Suzuki Burgman 400 5,500 miles December 22, 2025
Absolutely confidence instilling tyres in almost all conditions, only haven't tried them in snowy weather. Dry grip is comfortable and also enabled me to test the limits of my bike like I have not before. The majority of my riding happens with a pillion and both of us felt the comfort as we switched to these.

With my previous tyres, the wet grip was poor enough that I was being unnecessarily cautious to a point where they were taking my focus away from traffic. Now, the opposite is possible.

I try to use as less brake as possible with my riding style and the wear so far seems good, I am hoping to reach 15000km at least.

Unless Metzeler makes an even better tyre, I don't see myself buying a different brand or model. These honestly feel like the absolute best there is for all-year riding.

It grips very well on wet conditions, you feel every crease on road for me that's a downside comfort is a little low
