I too enjoy a good ole car v. bike run.
I came up on a very nice BMW in the Kern Canyon & he held me off in the upper part, which is alot of very tight 25-35 mph twisted madness, for quite a few turns. The times I thought I was going to get by him he was sliding just enough to scare me off
because I thought there was a chance he would drift over into me. Of course once the the turns went to the 40mph+ type of canyon carving with some nice short sweepers in between I went by & he couldn't hang
. I really let it go afterwards just to put some distance on him but I give the guy credit for his driving skills. Those beemers really slid well, very controlled & we are going downhill so it makes his acceleration better than if it were flat or uphill. Near the end of the canyon I pulled to the side just to see what kinda of time I had put on him. Nothing exceptional but enough to pull my sandwich out & eat about 1/2 of it. As he came by there was the friendly wave/thumbsup
from he & his passenger. We both had a good time.
Although the ability of sportbikes to out brake into corners & accelerate faster out of them usually means we are going to win I agree with LordDuckhunter's assessment of about the advantage of 4 wheels contact patch & lateral G force ability in the really tight corners. I may disagree with the roll-on matchup unless you mean literally a roll-on with out downshifting. I've not had the pleasure of going against a Viper in this type of contest (challenged a few but no takers) but every other kind of car I've gone against in this kind of race I've dropped it a couple of gears & it's see ya
. I know there are cars out there with a higher top speed than my R6, the Viper being one, so I'm not going to be too surprised when they eventually go by me. I just hope that it takes a mile or two & they are friendly about it
