I know you say it's your baby, but it is just an R6. It's not going to be a collectors item; get out there and put some miles on it! My R6 has 50k miles and runs like new. It was ment to be ridden, and ridden hard.
The really small (50cc) scooters just don't have the power to go 70. However, a 250 motorbike will get you down the highway without too much trouble. I'm looking at a 250 Nighthawk as a daily grinder. Not only will it save on gas, but it will save an absolute ton on tires. All other consumables (chains, sprockets, etc) will last longer with a 250 than a supersport.
