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.

I fitted these tyres after a Scotland trip with the existing trail type tyres, a couple of front end twitches and countless times the traction control kicked in even just on damp roads. With these tyres fitted a mix of high speed touring across France and Swiss alpine passes, prior to which some weekend riding with mates on sports bikes. Adjusted the fork preload and the tyres performed impeccably, even the day we had monsoon like rain. I had already sorted the pressures to my liking which were 36 front and 38 rear, with or without full luggage. The bike has limited adjustment on the suspension but only required a few clicks on the rear between fully loaded and rider only. I&rsquo;ve always ridden sports bikes until recently but my worries about grip handling the tight switchbacks on such a heavy bike were very quickly dispelled, No real signs of wear yet I&rsquo;ll have to see how they do for longevity, but no hesitation at buying these tyres again. I have Avon sport tyres on my Honda VTR SP1 and these tyres give the same feedback and a very comfortable ride. Front 110/80R19. Rear 150/70ZR17
