Hi, I had a bad experience with my last bike with different make of tyres front and back. So when i changed my REAR tyre on my 400, I made a point to getting the same Dunlop tyre as stock which works fine for me. I am nearly ready for my next replacement REAR tyre again. Will a be able to change to any make REAR tyre of which I find the best value on the 400. On my last bike I changed my stock FRONT tyre from a Bridgestone to Metzeler and the bike was very hard to control at speed.
