Tyre size:
What tyre size do you require?
The exact size of a tyre can be found on its sidewall.
The following chart shows you how to read a tyre size.
1. Overall tire width in mm
2. Ratio of tire height to tire width in%
3. Tire design: ''R'' = radial tires (widely used), ''D'' or ''-'' = diagonal tires (rare)
4. Required rim diameter for this tire in inches
5. Key figure for tire load capacity
6. Key figure for the permissible maximum speed (speed index)
7. Motorcycle tire identification, tires only approved for motorcycles
8. DOT labeling
9. Date of manufacture of the tire (week of production / year of production)
 
/
SPEED INDEX:
The speed index indicates the maximum speed intended for the tyre. Up to this value, the manufacturer guarantees optimum operation with the appropriate tyre pressure. The maximum speed allowed for this vehicle is given in the vehicle owner's manual; this information can be used to select the appropriate speed index for the tyre. The speed index is the last mark on the sidewall of the tyre.

A good tyre. More than capable on and off road. Although tread isn't aggressive enough fir real muddy conditions. But would buy and fit again.

04.03.2019 from Tomaz
Very good milege 16k km regional roads, country trails soft offroad, very good for dualsport, noisy when cornering. Grip is good, when it goes does not slip all the way. The front tyre could have a little more braking power on pawed road and back tyre could have softer compound on sides.
28.09.2015 from steveR
This tyre last better than a TKC80 and in anything other than mud, are as good gripwise, at least on the rear! Wear suffers, even on a lightweight, with a laden bike in hotter conditions I found.
25.02.2015 from Chris Gilbert
This tyre has given me lots of confidence on and off road. There is ample grip on the rough and gives a smooth safe feel on the road.
