So, to set the scene, these tyres are one of the O/E options on Honda 750 Transalp's. Note - transalp's spoked wheels are not air tight and they run inner tubes. The tyres are surprisingly quiet, given the 'blocky' off-road look of the tread pattern. Warm up is quite quick, but make sure they do warm up, as grip can be a bit iffy when you've parked up for a while. Side grip, front and rear, is very good and you will be doing very well to run out of grip while cornering. Under very hard acceleration you can get the rear to squirm a bit but I've never had it let go on me. The braking performance is very good and I've yet to operate the tranny's ABS in any conditions. Corner entry is very smooth and they hold a line perfectly, easily as well as a full on road tyre. Direction changes are equally smooth and on the slightly positive side, meaning left/right flicks are a pleasure - even with a 21" front wheel. Straight line stability is very good until the rear starts to square off a bit, at that point a bit of instability starts to creep in but only at naughty speeds. The only fly in the ointment seems to be durability, I only managed 3,544 miles out of the original rear tyre. It was down to 2.2mm in the centre and had started to square off, affecting stability and turn in. The front tyre is like new and hardly has any wear? That's the only reason I've gone with another rear.
If you want a chunky looking tyre that has masses of grip then this could be for you. If you want to get a bit of mileage out of your tyres I would look elsewhere...
