If the tires were rock hard, the sidewalls should be cracked. I've been out tossing the bike around my favorite curvy road every day since I bought it. Hasn't been one slip on either end when I'm out there. I'm not flogging it at this point, just riding it nice and easy. This bike has way more power than any bike I've ever owned, and I'm showing it the respect it deserves until I'm comfortable with it.
In the past I've owned two Honda CBX's, an 83 CB-1100F, an 89 Suzuki Katana 1100, an 83 Suzuki GS-1150ES, and many others. Been riding since 76. This bike puts way more power to the ground than any of those. Plus I've only had the M109R the last 11 years. It's not stock, has a 2-into-1 exhaust, intake and fuel tuner. It's a pretty powerful bike in it's own right. But it still weighs almost 750 pounds with a full tank, and only makes around 130 hp. It's nothing in comparison to the King.
The tires on the King are getting close to needing to be replaced, and I'll be doing so soon. I have always just liked to get every mile out of a tire before doing so. At least I'm not one of them fools who goes "to the dark side", and puts car tires on my bikes.
Let me say it again then.If your tires are older than 5 year old you better replace them.These new compounds are not showing any cracks but get hard to a point when you have zero traction.
This tire was on the bike when I bought it and I was sliding all over the place just like I'm in the rain tho the tire looked in good shape.The color in the thread is still shoving too.It was made in 05.10.2009. and I got the bike in Oct of 15.
I'm not new to this either riding since '86 my list is way too long to mention every bike I had own/ridden but all I can tell you that you don't ride on the bike you ride on the tires.Please for the love of god spend that $200 for a new set of tires.
