I have a 2012 Burgman 650 with 26,000 miles on it. It has run flawlessly since new. I was all geared up to go on a ride today and the bike all of a sudden is very hard to push forward or backward with the engine on or off. If I cracked the throttle on a bit it moved forward then stopped when I closed the throttle as if the brakes were applied. All motorcycle shops are closed on Sunday and Monday in my area. Very depressed. Any suggestions what could be the matter?
