Help decide on next bike

[Sinfix_15]

This one is simple. If it's going to be a street bike, get the R1. It's the only one liter on the list.
If its a track bike, then get a 600.

I dont understand the "bigger is better" approach to street bikes. I tend to enjoy throttling a 600 vs having to show restraint on a 1000.

I dont plan on going to the track, just mountain carving
