crock stock Wrote:so can formula xtreme bikes race in the junior manx?
i suspect that this new gp series will be even more '1-off' than those bikes but it'l be interesting

In a word yes

The rules for the Junior Manx GP as copied from the regs

Race 4 JUNIOR RACE
201cc – 250cc 2 stroke 2 cylinder
550cc – 600cc 4 stroke 4 cylinder
601cc – 675cc 4 stroke 3 cylinder
651cc – 750cc 4 stroke 2 cylinder

The only other restriction is that tyres must have a moulded thread. NO slicks NO cut slicks NO threaded tyres with cuts

You can do absolutely anything you want with your bike so long as it complies with the general rules of construction and is within the capacity limits
