Based on the numerous past threads on tires it seems as tho you are experiencing normal tire wear for the OEM B'Stones. Most have reported 5000-12000 with 8,000 miles being the average for the rear and almost double that for the fronts. Of all the different types tried most end up with a combination of OEM front and something else on the rear, depending on what works best for their style of driving and road conditions in their area. Several others and I have found that the Michelin Pilot Sport Radial rear and OEM front to be a good compromise combination.
There are so many variables affecting tire wear that your results may vary.
The important thing is to ensure that you have good bearings, tires properly balanced and inflated to proper pressures.
There is a large "normal" range depending to the type of riding you do. If you're in the twisties, or the mountains, your rear tire wear is normal. Your front tire seems to be wearing faster than normal. At about 15000 miles I'll be replacing both tires, the rear for the 3rd time (fourth set), the front for the 1st time. (I started getting the cupping effect on the front tire at about 12k miles).
OK.. What riding style works well for the Michelin Pilot sport? I am at 6400 miles and my rear tire seems OK.. but DOES have a flat area on the primary wear area.. decent tread.. but.. so I expect that at 7,000 Miles I should get a new rear tire have been wonderinf what to get.. I put a new Pirelli Diablo on the rear of my last bike.. It seemed OK.. but I traded it before I knew whether it was great or just OK..
New to Burgmans, most of my experience is with Goldwings. When the 1800 Goldwing came out Honda switched from bias to radial tires and all the Goldwing faithful complained that the earlier models with bias ply tires got over 20,000 miles out of their tires, the 1800s were getting 5000 to 8000 miles out of their new radial tires. My question is does anyone make a bias ply tire for the Burgman?
