Hi guys and gals, I'm after your thoughts on these two machines. I'm looking to buy my first bike, like nakeds, won't use it as a commuter, but will be doing a lot of highway mileage. Riding position is nice with both of them, CB500F is a bit better for my long legs. Important differences for me and the ones I'd like your opinion on: CB400 CB500F Built Japan Thailand Engine 4 cyl inline 2 cyl parallel Front brakes Twin disk Single disk 285mm 320mm Ground clearance 130mm 155mm ABS Optional Standard CB400 has larger fuel tank that could be added advantage. There are plenty of second-hand bikes available, but lower mileage ones are still around and above $8000. CB500F is newer so not so many of them available second-hand, but a brand new bike comes around $1000 less than CB400. So my questions are: Does CB400 have better/smoother engine than CB500F (inline 4 cylinders V parallel 2)? How big an advantage is front brakes with twin disks? In what situation bigger ground clearance might come handy? Is there any evidence that build quality of CB500F is inferior? I'm in "get ABS" camp simply because I'd like to have peace of mind and additional safety feature if it is available. But it doesn't mean I won't learn to brake properly and safely in any situation. All help and advice is muchly appreciated Thank you!
