What’s New:  There are a couple (see No6 & No11) of late technical rule changes, see extracts below from MCUI-UC Technical Bulletin.

6. REAR SAFETY LIGHT – Red Rear Warning Light (Rain Light)
All motorcycles must have a functioning red light mounted at the rear of the machine to be used in rain or low visibility conditions as instructed by Race Control. The Rider must ensure that the light is switched on whenever a rain tyre is fitted on the motorcycle and/or when any practice or race is declared “wet” by Race Control.

Red Rear Light must comply with the following:
• Safety lights must be of a robust quality and securely fitted in the approved position.
• Lighting direction must be parallel to the machine centre line (motorcycle running direction), and clearly visible from the rear at least 15 degrees to both the left and right sides of the machine centre line.
• Mounted on the seat/rear bodywork approximately on the machine centre line, in a position approved by the MCUI Technical steward. In case of dispute over the mounting position or visibility, the decision of the MCUI Technical Steward will be final.
• Power output/luminosity equivalent to approximately: 10 – 15W (incandescent) 0.6 – 1.8 W (LED).
• The Safety light must be hard-wired into the machines power supply
• The light must be able to be switched on and off and via switch mounted on handlebar.
• The MCUI Technical Steward has the right to refuse any light system that does not satisfy this safety purpose.
• Machines not showing a functioning safety light will be black-flagged and will not be permitted to continue practice or race
• Flashing light not permitted.
• Pre73 Classic machines ,Two stroke 125GP, 250 GP & Classic GP machines and motorcycles with a self-generating ignition or “total loss” system are exempt from hard-wired into the machines power supply but must be of suitable design and robust quality.( no bicycle type lights permitted). (ICC Dec 2024)

Rule 11 Oil Filter specification for all racing classes that use spin on/off style oil filters. As from start of 2025 racing season all screw on oil filter/canister type filter must be as per OEM design. MCUI technical will not be permitting aftermarket performance oil filters with fabricated nut for tightening/lock wiring point due to potential over tightening and causing damage to the filter housing. Only OEM style filters will be permitted and must be secured with a jubilee clip to stop filter untightening or used as a locking wire point to secure to engine /chassis point (ICC Dec 2024)
