TBS - insurance
You may find that it depends on the insurance company. I tried State Farm, Progressive and GEICO when getting quotes for my 98 TBS.
State Farm was a little high, GEICO got my $$ for price and over-all coverage, but Progressive categorized it as a Sport Bike (with significantly higher rates) because of the wheel size! Apparently that's a significant factor in why sport bikes are a higher liability ride...
You can do quotes online pretty easily anymore, so you don't need to guess.
