Std. RMK
Yup, It's a standard RMK so it stays cool, the motor runs 120 degrees max. The jack shaft is solid and stronger, it has more bogie wheels on the rails, it has a solid snow flap which also helps with the cooling of the motor, an extra cooler in the tunnel (why it runs cooler), and is just begging for a turbo, with an air to water intercooler!!! Add some aftermarket shocks that you would want on any sled anyway and it'S a GREAT machine!!! Anyone on a budget can see the value here. Just my 2 cents.
