+10 on the seat good advice here. I can barely fit in mine but then as soon as I get moving I don’t even notice.

Run c12 you’ll be glad you did. When I first started w the S-M 125 I used 98 pump gas and after 6-8 weekends had a detonation ring which made both the head and cylinder worthless. That was over $350 to replace. I generally run 4-5 15min sessions on a practice day and rarely use more than a gallon to gallon 1/2. At ~$20 a day in gas for the c12 it’s a good investment. Plus if you’re planning on tuning a pwk/pwm with the right jetting race gas will help a lot in giving you stable readings.
