I've heard you can squeeze car tyres on as they are cheaper than fancy motorbike tyres and last longer
Some one once posted "how long does a tank of fuel last".... and I answered truthfully "just under an hour if you are riding it right".
.......but if you decide to put one on your 848.......... https://www.ducatiforum.co.uk/threads/mosfet-regulator-installation.68657/
I had one and proud to admit it... didn't have a car license, but did have a broken leg and arm then needed to get to work.
I bought a Lithium battery for my Monster. It was very good but I had to buy the right charger otherwise I would invalidate the warranty. Smashed up the bike and never saw the battery again :-( I now need a battery for my ST3 and would look into it again. They are more expensive but light and about 2/3 the size of a normal battery.
I'm innocent! The police have cleared me of any wrongdoing - I think, but have yet to see their report
