Time tested: Five months/2500 miles
What’s good? Should you be unhinged enough to want to take a 650cc trail bike on a trackday, you need these tyres. I fitted them myself to the wheels of the XT660R I share with my son Fred, since then we’ve done 2500 miles of A-roads and city commuting.
In those conditions, the tyres are entirely predictable and have no vices. Confidence in hissing rain is particularly good; they are so narrow they cut through the water more easily than sportsbike tyres.
But it was an evening trackday at Cadwell that knocked my socks off: masses of braking confidence, and enough cornering grip to duff up averagely-ridden sportsbikes. Whizzing round Chris Curve at 80mph with my foot on the floor was both surreal and hilarious, but mainly hilarious. And this is from a 90/90-21 front and 130/80-17 rear.
I used 30psi front, 35psi rear on road or track (a bit more than Yamaha recommend) with no bother, and they didn’t overheat in a 15-minute track session.
What’s not? Wear rates suggest the rear will get to 5500 or 6000 miles which is reasonable but not amazing for a 47bhp bike.
