I enjoy making progress and whilst the bike handled OK two up, it didn't turn in very well solo. By 3k they were on the way out and by 3.5k it was sliding around all over the place.
I fitted BT- 023 as they were all Strathern Tyres in Crieff had in stock and I needed new tyres to get home from a funeral in Perth. They've completely transformed the handling and it turns into corners solo like a GS or VFR now
