I'm not bothered at all that it is a niche bike, that is why I bought it! I love that it is unique and turns heads, and I knew that after buying it, I never intend on selling. I love this bike.
What I'm getting at is the R3 has been out 10 years now and you can mention it to a lotta guys who ride and they say "What's that?"
Nothing wrong with it, but from a market standpoint I understand why it hasn't been dethroned in terms of cc. I think if anyone would dethrone it, it would be Triumph to do it.
