As the proud owner of a nearly year old XT660Z I find I'm having a few wet weather issues, 3 times now I've braked hard in teh wet to find the back end viciuosly sliding. First time was the day after I bought it on the motorway round Glasgow in rush hour, speed about 15mph or less, 2nd gear, I'm slipping into a gap when the car to the left of the gap came into the gap I was going into. Ended up full sideways across the lane, 2nd time was on a fast trunk road in pouring rain, slowing for a roundabout and again ended upsliding on full right lock towards the roundabout. I was travelling in top around 50 mph. Gently released the brakes and straightened up. Third time was on a muddy, wet single track road, speed about 40 in 3rd, robust braking for the right hander coming up and yep, the ****** slid at the back from side to side 4 times. Released the brakes again and slid down the side road (twin muddy ruts actually). It copes with the mud pretty well and the slides, though initially quick and vicious, are controllable, at no time did I feel like it was going down.
Tyres are Michelin Sirac (4000 miles old - plenty left on them) rear suspension is on 3rd notch, front suspension is reportedly 3 turns harder than standard (haven't checked this yet) tyre pressures are 30 / 33 F/R.
Now it's quite possible that I'm a lead foot on the back brake (Previous bike was an Aprilia Caponord Rallye, which had a back brake that you could stand on with both feet and a heavy mate on your shoulders and not lock it up)
So, is it me? Would sftening the suspension help, are the tyre pressures right? Or are Michelin Siracs not that good on wet tarmac?
