Nankang XR611 Rear 225/50R15 - fitted to RTL
Today was my 1st day with the Nankang XR-611. Some info that may be of use to someone.
Size
Bike
- 2017 RT Ltd with Kendas still on the front
Journey
- 300km with a mixture of highways, freeways, and city roads.
- No additional Cargo, just an afternoon ride.
- Rear Suspension set on Minimum (factory shocks)
Occupants
- Two Up (me 90kg, pillion 55 kg)
Speedometer accuracy
- Speedo now reads 4% lower than actual speed, down from from 3% with the Arachnid
Pressure
- 26 PSI down from 28 with the Arachnid
Ride
- I expected the stiffer construction of the tyre and sidewall to create a harsher ride which in some ways it did, but the heavier un-sprung weight (the tyre itself weighs 9.5 Kg) seems to counteract this. Even my pillion (Wife) noted the ride felt firmer but not harsh.
Handling General
- The tyre does not track the irregularities in the road like the Kenda or Arachnid
- Accelerating out of corners with a patchwork surface where the Kenda or Arachnid rear tyre would step out and skittle across the imperfections has gone.
- No additional over-steer was experienced, nor under-steer for that matter.
- The tyre feels much more confident on the road at higher speeds up to 130km/hr, and the Spyder itself is more confidence inspiring with the tyre.
- Sidewall roll - an improvement on the Arachnid gievn the lower pressure. The bike feels quite direct when swerving to miss objects on the road
- ABS - the back wheel appears to be able to share more of the breaking power when Hard stopping. In the place I like to test my cars and bikes the Kenda and Arachnid would skid, this did not happen with the Nankang
- Because I still have Kendas on the front I haven't measured any difference in stopping distance. I will get a stopping distance reading before sending them to their rightful home - the waste management facility.
Wet Weather
- Not tested, will report later
I have tried to communicate the types of things I would report when testing tyres on two wheels to my sponsor. I look forward to seeing and reporting what the tyre is like in the wet with things like grip, aquaplaning, braking and anything else I find. Hope it helps in your choice of tyre
Disclaimer
- You might get very different results but, at least these can serve as a guide to your tyre selection.
- Coming off Kenda to the Arachnid felt a big improvement, so coming from the Arachnid to the Nankang seems ....... um .....um .... chalk vs cheese, poorly made beer vs masterfully crafted beer...
