Maybe change the prefix to kr? For Kart Race?
Besides that, it's looking nice. I like that you've given a section with 2 very distinct paths. One that's faster but may slow you down due to the sharp turns, and one that's longer but less turning. One of the key things many people (myself included) forget when mapping is to make each route provide a different possibility of play as another. EG, faster to point but less cover over another, slower route. This is a good example that I think will be used frequently in "good" kr maps. Length/Turn types (sharp, long, how many, etc)
