your duke is quite fast for a big single and was out Accelerating my ZZR600 Smile

. increasing the capacity (if possible Thinking

) will only weaken the engine.

Don't think so, my mate trashed his and ended up with the std bore.

Its already 640cc, do you really need anymore, plus its a supermoto.

People, who after blowing there engines up, always go for a bigger bore whats the point???

The bore the engine came as, i.e 125 or 640, means thats what the bottom half of the engine is DESIGNED AND MADE FOR, so putting on a bigger barrel will only reduce your engine life and the next time it goes bang you might be looking at more damage

think about it

Anyone agree??????
