Yup 55,s for me always used them as I think d211 and d212 dunlops only use this profile . I do notice the difference with the 50s on my new blade and that's just on the road
Personally. I think you can spend all your time chasing the perfect set up, tweaking here and fiddling there (That's not a wise crack at Jimmy Savile either ) But I'm all for trying new things and seeing what happens. Anybody got any thoughts on projector lights? Probably best to start a new forum...lol
I went to a 55 section last year and was really impressed with the difference in feeling. The bike felt significantly quicker to tip into corners and more stable when it was on lean. Much more agile feeling. I wouldn't want to go back to a 50 after this.
They would no doubt say the tyres are not intended for fitment by the bike manufacturer and therefore your insurance is invalid.
I say there is very few of us on here that are fully covered. here is a quote for you "Sometimes we just can’t resist tinkering away with our motorcycles. The shiny new end can begs to be bought, keeping you awake at night with thoughts of its low rumble. Not only do modifications look cool, they’re usually fun to fit too. You must declare to your insurance provider any modification you make to your bike that alters its standard form, even if it doesn’t affect your bikes performance. Many modifications will not alter the price of your premium in any way. Crash bungs, tank-pads, suspension, braking and even up to a 5% engine capacity increase usually do not have any impact. It is a common concern that the insurer will instantly whack your premium through the roof at the slightest whisper of that performance exhaust, but this is not always the case. You should check with your insurer prior to modifying anything on your bike so you can discuss any price changes beforehand. Failure to inform your provider would most likely result in them refusing any pay-out in the event of an incident; especially if the modification played a part in the claim or increased your machines power output. Even fairings and screens must be declared. Whilst a new fairing probably won’t make your bike go faster they can add aesthetical desirability to your machine. This in turn makes them more attractive for bike thieves. "
