When I used to ride cruisers I looked into going darkside and did a lot of research into it
It’s a very good idea and has a lot of benefits (longer tyre life, greater contact patch with the road and better grip as CT’s can have a softer compound)
It all sounds great BUT after speaking to a few cops
and insurance people it was pointed out to me the BIG downside,
(as Streak said) when you run a CT on a bike it will void your insurance
(both normal and 3rd party) and that is why Police will take exception to people doing this…
Although I have heard rumours of people having it listed as a modification with their insurance and getting to legally run a CT on their bike but I’m not sure if this is true or not…
It’s a shame but that seams to be the way it is
Run a CT on a car and a bike tyre on a bike, or do what you want and take the risk
