I find the bike fairly heavy but quite fast enough for my needs. It has more torque and power than the 550 and feels more secure on the road. I have had no real problems with the bike as it had only covered 4,500 miles when I bought it a year ago. In effect a new bike. It has had a slight oil leak from behind the gear shift casing. It’s intermittent so difficult to trace and irritating rather than a serious fault. Most parts are cheap enough. Tyres have lasted well. Both have now done 6000 and the rear still has plenty to go. The front is about half worn. Very pleased with the bike and no plans th change it.
