No-one ever says "That's not a motorcycle" to me about my Spyder after I've blown them into the weeds thru the twisties & short straights of the Adelaide Hills or on any of the nearby tracks!
The comments are usually much more complimentary and astounded at how well my 'rocket-sled on rails' so comprehensively out-corners & out-brakes their clunkers on 2-wheels in the tight stuff; especially at how far in I can push it into, and how fast I can keep it going through the corners; and if I do need to slow any &/or brake hard part way through, at how stable doing that is and at how early/fast I can get it going again heading out of the corners!
Mind you, it's only some of them who ever get a chance to say anything when/if they do eventually catch up and pull over for a break where/when I'm usually finishing my break!! All the others are so far behind that they never catch up &/or get a chance to say anything to me!!
