I fitted these to a 2010 YZFR6. Gentle riding on first 150 miles. Used t/o Summer & Winter - current.
Both Front & Rear tires have a hard compound centre which helps with wear.
Both F & R tires have sound micro grippage - where the tire forms into the surface, but it needs smooth handling to do so. Macro grip is pretty standard stuff.
Fantastic dry grip on the F tire, with no slippage at lean angles on A & B roads (65 - 85mph). Doesn't like gravel just like any other tire so add caution. R tire needs loads of heat before grip's affective (4 miles dry avg. 65mph). R Slips on dry too often in town with hard braking, but good cornering characteristics & responsive.
F & R hold their own in the wet, with more confidence in country bends on wet surfaces (@ 65 - 70mph) than dry funny enough, but caution on soaked surfaces with only macro grip taking effect. The F tire offers good drainage, R tire keeps up fine with good grip on the edge.
On M roads (60 - 1600mph) & track there was no issue with grip & handling on turns & overtaking. Responsive R tire.
Back tire needed replacing after 4500 miles, 6000 for the front. Wish I could've had more.
Comfy & R6 don't go together!
Priced around the same as Avon Viper Sport AV59's. Ok price.
Great for starting out on race track.
