I did two track days at Thunderhill in Northern California last weekend. I had a great time, but was running even slower than usual due to it being my first track day in 20 months, and not having any track skins yet.
I was running a leisurely 2:30+ per lap. I had the suspension dialed in on Saturday, and had scrubbed in the new Michelin Pilot Power 2CT tires.
On Sunday I let my friend take my bike out as he wanted to try it, and had never ridden an F4 1000 before (only a 750). My friend has been riding about 15 years and is quite fast. He was running 2:05 laps on his 1098S.
On my bike he was having some fun, but not pushing it too hard as he didn't want to do anything crazy. He estimated he was running about 2:20 laps and came in about halfway through a 20 minute session. He got an unexpected tire slide going into turn one and a more unpleasant slide of 10-15 feet in turn 4, while on his knee, before the front tire hooked back up.
When he came back in, you could see that he was running off the front tire on my bike. On his Ducati 1098S there was 3/8" on either side of his front tire that was clean, and he was charging the corners much harder as evidenced by his much faster lap times on his bike.
He told me to post up here and see if you guys had any ideas, since this model bike has been raced at the national Superbike level, and should obviously be capable to going faster than that without these issues.
I have a 120/70 on the front, and a 190/50 on the rear. I'm a size 56 Euro and he's 52, so the weight difference between us isn't that big. He had race tires on his 1098S, but gave my tires a couple of laps to warm up.
Ideas???
(I'm assuming this is something that can be adjusted and not inherent to the geometry of the bike.)
