I’m setting up a kart for my son to try Yamaha Sportsman, need a seat for his scrawny butt. His other kart has a DR Kart seat on it, and it’s a ‘mini’ size. Not sure who the manufacturer is on it, but I’m assuming DR just re-brands someone’s seat. He’s 9 and a little small for his age, but not tiny. Seat doesn’t have to be flawless, but swiss cheese won’t do us much good, either.
