Great bikes, very impressive collection.
That Suzuki 500J has very little torque in low rpm what lead to ride reeving and when one need the brakes you will discover the drum brakes are anemic.
The GTS1000 not impressive in photos but live in real metal its a superb bike see let alone ride.
The GoldWing is the most silent bike I have see to date, this bike has class, I also have see a broken crankshaft from this bike and it have little metal, not appear robust imo.
The Norton Commando is a running vibrator, twin cylinders crankshaft 360º.
