Why not measure around the pulleys to get an approx length?

Std belt is 809218300 superceded by 809218450 which is approx 880mm long (880;882;884 depending upon manufacturer)

Thank you for that information! I'll now work out the new needed belt size

For future reference when using a 100mm diameter crank pulley you will want belts which are about 50mm shorter than stock
