Roundabout + New Tire? = Gear Test

I always hoped I wouldn't have to post in this section but here's my story.

I started the day off with taking care of all the maintenance on the bike: new rear tire, oil change, check valve clearance, etc etc. I take off from Denmark and make my way towards the road I want to head to Germany.

Leaving town I go through a roundabout at around 45km/h (27mph) mid way through my bike slides out from under me. We finish the roundabout together via sliding, which is not the preferred method of travel. I get up and do a quick body check and then go pick up my motorcycle. I may have almost lifted my bike to far and dropped it the other way, luckily I still had enough adrenaline to save it.

The road was pretty good, a few rocks here or there but nothing noticeable. I just finished riding over a 1000km of twisties along the coast of Norway so I was pretty comfortable with the bike and my lean angle wasn't as extreme as some of the stuff I pulled a couple days ago.

The gear did what it was suppose to, I only have a small scratch on my forearm, my knee cap, and then my hand got tweaked from something hitting it or it getting twisted wrong.

Cortech GX-Sport 3.0 jacket:



Tourmaster Caliber pants:



Damage to the bike: quite a few scuffs on the pelican case, front fender, and it tweaked the handlebar. I will grab some pictures of it tomorrow when it's light out.

Lesson learned: don't push new tires that hard and maybe slow down a bit when driving in circles.

Glad you're OK. New tires are certainly a mixed blessing!!!

You'd think that tire manufacturers would figure out a way to wash/scrub the mold release off by now. Or that retailers would have a service they could offer.

Probably about 10-15 miles. I knew about how new tires can be slick, but I wasn't thinking.

"Mold release" is not it, at least according to the manufacturers. The rubber is just greasy until it has been ridden enough to get up to temperature, preferably a couple of times. "Scrubbing" in tires is not as critical as just getting them up to operating temperature. Or so I have read.

I believe in scrubbing in over operating temp. - I've put on enough new tires in the middle of winter with no way to get a tire as warm as stone cold summer tire. No issues as long as I can go through my usual scrubbing ritual. Maybe it's mold release, maybe the tire surface just need some pockmarks.

Anyway, I also believe those roundabouts tend to be a bit like freeway on/off ramps - slippery from cage droppings. Something about how dangling droplets of oil, diesel, coolant are sudden shaken off by the change in G-forces... In contrast, regular twisties have constantly G-forces.

I have an angle grinder and flap wheel removes almost no rubber, but leaves a nice roughed surface that does not slip for me. Take few minutes, then I balance tire.

Like these

The first thing i do when i change tyres is washing the bike. I go directly from the garage to the wash-shop.
