Ive had my Class 6 for 20 years, and rode dirt bikes since age 4... just to get my qualifications out there on this topic.
I scraped my best friend off the road last summer. He was 35, and riding his first bike, an XRL650 (Honda dual sport). His femur was sticking through his jeans. He had zero preparation (or respect) for the amount of power he was sitting on.
If you are a beginner, and unless you are a large man (200 lbs +), you have NO BUSINESS being on anything bigger than a 400cc. I cant stress enough that people just dont appreciate the power to weight ratio modern bikes have.
Besides, ICBC rates almost double after 400cc... Stay below it, for your own good.
check this one (upon a ten second CL search). Looks mint! (note all the classics in the bacground) Stylish, vintage Honda. Its called a 400 but technically is 399cc, so you make it under the insurance premium tier. k's a little high but these old Honda's go forever and are too easy to work on.
