My bike, bought specifically 1 year ago, came with T30’s, I did ask at the time if I could have different tyres as there was wide variety on the showroom across all bike and they said no, it’s as come from factory, so I assume luck of the draw?!
Just changed tyres last week to Roadtec 01 and it’s an unbelievable set of tyres(had them fitted on my S1000R as well before the XR)
On the T30’s I did 7200miles, lasted exactly 1y2w and I wouldn’t say they’re rubish, just not nearly as good as others can be... the worst part about them for me is that during the last 500 - 1000miles I felt every pebble, road fault, everything.
