Completely different tyre. NS2R are a good fun budget tyre.
AR-1’s however are a LOT grippier, have infinitely stiffer sidewalls and won’t overheat anywhere near as quickly.
But they’re about double the price.
Depends what you want from your tyres really.
@Breamy - can you remember how much you paid for the AR1’s back then??After reading this i bought a set, night and day difference! Absolutely loved them today at blyton
