I have PR4 trails on my Tiger800 (4000m+). The trails come in 'adventure' sizes and are V rated, otherwise look the same. very pleased with these tyres, biggest surprise for me was how they improved the ride of the bike.
Just put a pair of PR4s on my Sprint ST. The BT-023s that it came with were fine, but the rear had become squared off and a slow puncture helped me make up my mind. I've not had the bike long and have not yet used it in the wet either on the BT-023s or on the PR4s. However, the PR4s have, so far, been very sure-footed. Slightly quicker turn-in at lower speeds than with the Bridgestones; I doubt that I ride hard enough to give a useful opinion. Let's see how they behave in the wet........
I'm on my second set of PR4's Great in the wet and good mileage. Dry grip far exceeds my capability's.
That's good news then..... the dry grip was great on a run from Stroud to Hereford and back through the lanes on Saturday afternoon. I have had a slight front-end slide on the BT-023s before but not yet found this with the PR4s. (Raining here now so I'll go easy today!
just bought the mich 4 trail from oponeo on net 173 for pair luvvv them west coast scotland grip like bugger in all conditions ( as it rains and I live on a caravan park all up hill ) front seems slightly slim but grip is a great confidence.
