I would like to propose the following change to the Supertwins GTU class. Section 4.2.1 item 3
As it currently reads:
SuperTwins GTU
• Up to 750 cc two cylinder, four-stroke (excluding Ducati 749R)
• Up to 250cc two-stroke
• Up to 995cc two cylinder, four-stroke, two valves per cylinder, air-cooled
• Unlimited displacement single cylinder, four-stroke

I propose the rule read:

SuperTwins GTU
• Up to 850 cc two cylinder, four-stroke
• Up to 250cc two-stroke
• Up to 995cc two cylinder, four-stroke, two valves per cylinder, air-cooled
• Unlimited displacement single cylinder, four-stroke
