There is an issue with that dealers website info on the WR. It has, according to yamaha, a 6-speed. His site says 5 speed. All things being equal I would take the WR with fuel injection for a road legal bike rather than the kawi with carb.....FI should more than make up for the 15lbs. Yamaha is a better made bike, IMO. Dont look at length, look at wheelbase. The yamaha is than an inch shorter there. Usually a shorter wheelbase will mean the bike is quicker handleing......but an inch isnt going to do much. I know the yamaha has a better suspension too.
