There are multiple ratings for octane in use around the world, primarily used to keep the public consumer totally confused so that "branding" may dominate consumer choices instead of relevant data.
MON Motor Octane Number
RON Research Octane Number
PON Pump Octane Number"
AKI Anti Knock Index
However, the bike, with its 9:1 compression ratio, will work fine with the lowest grade gasoline available at your local filling station. Don't use diesel fuel.
From Wikipedia:
Different countries have some variation in what RON (Research Octane Number) is standard for gasoline, or petrol. In the UK, ordinary regular unleaded petrol is 91 RON (not commonly available), premium unleaded petrol is always 95 RON, and super unleaded is usually 97-98 RON. However both Shell and BP produce fuel at 102 RON for cars with hi-performance engines, and the supermarket chain Tesco began in 2006 to sell super unleaded petrol rated at 99 RON. In the US, octane ratings in fuels can vary between 86-87 AKI (91-92 RON) for regular, through 89-90 (94-95) for mid-grade (European Premium), up to 90-94 (RON 95-99) for premium unleaded or E10 (Super in Europe)
