I recently got my full license and now have the itch to upgrade my bike. Currently I have Ducati Monster 659. Ducatis are nice, but I cringe at the price of the fast ones. Went to the shop last week and two bikes attracted my attention: Ninja 1000 and Yamaha FZ1S. Both are light and comfortable to sit on. Couldn't test ride them yet because of the miserable weather in Sydney, but planning as soon as. Does anybody have any of those bikes? What are your impressions? What are the weak points? One of the things that are important is the comfort of the passenger seat. I would appreciate the opinions.
