motorcycle question

[Filliam H. Muffman]

Any bike over 400 cc that can not hit 90 mph is either way under geared or is using lawnmower technology. The 60's era Honda CL90 I rode in high school could hit 65 mph with a hint of a tailwind. The 1979 Yamaha RD400F (a :quotes: small :quotes: bike but not a beginners bike) had a top speed right around 100 mph.
