500

Is there any RPM or SPEED limits for RC390 before 500 or 1000 kms ?

So it's now official that my local track orginazation LRRS in New England will not be allowing the 390 run in Formula 300. Instead they will be adding 500 class for it based on CCS's 500 Supersport class. The rc390 will compete against the EX500, GS500 and so on. Not sure how many on of you...
