I live close to Sonoma and want to take advantage of the kart track days they have and need advice on what type of bike would be best. I have two options close to me, the first is a 07CRF150 supermoto set up and the other is a KTM rc390 both at good prices. I do not race but enjoy doing track days (about 10 a year) on my 13 675r. So the question is, which bike would benefit my riding on the trumpet more? Or should I just spend the money on more track days (easier said than done with life commitments)? Thanks in advance.
