My GT502 radial rear lasted about 4,500 miles. These tires come in the exact same sizes in radial so should be fine in that respect. Just looking for thoughts or opinions. Would like to get more tread life. Could not find any matches so put another stock rear on, but looking for next time. Other brands do not have matched radial sets, can find a few radial fronts but only bias rear. Thanks

 

Interesting to find out info on mileage and performance

Harleys routinely use bias rear tyres, which is an option to consider, your bike is unusual in using a radial. The other Sporties that do are the SuperLows, which use a 150/70R17 and have the same problem you identify.

Avon make suitable Storm 3Ds for both, but in 160/60R, so a little wider, which offsets the change from 70% to 60% profile. I recently fitted a Storm to my Firebolt, to replace a Metzeler Z8 which gave me great mileage, better than your GT, so that is another option to consider.

Bear in mind that radial tyres are routinely aimed at the sport bike market and are unlikely to give high mileages.

 

GR, you have completely missed the issue that Roadster owners have finding tires their bikes (currently that is)

 

In what way?! We SuperLow owners have a similar challenge, neither size are commonly available yet from other brands.

 

In regards to the statement above...


A Bias Rear really is not an option in this case

Following the NO Radial Front WITH Bias Rear adage...

Although you can find Bias 150/70-18 Rears easily, you can't find Bias 120/70-19 Fronts



Additionally, easy to find Radial 120/70-19 fronts but not a great selection in Radial 150/70-18 Rears


Believe me, Switchback12 didn't just start looking for tires
