Hit 150 twice on my 86 VFR 750F. Both times on Sunday morning on a velley stretch of Pa Turn Pike NE extension, no one on the road and no wind and no where for the man to hide. The bike felt very stabel and had some throttle left, but that was her red line and with 50K miles on her a 150 MPH thats fine for me :) . Tunnel vision is a strage thing as you try to adjust you vision up the road for the speed, everything just appears to come out of the same spot! Dashed lines are more or less a solid flasing kinda thing. Oh and the toll takers look at you very mean like when they see you just went 10 miles in about 4.5 minutes :) .
Been up around the 90 to 100 MPH mark on dirt bikes, Had a IT 250 geared up for long wide coal roads, the WR 400 get up there with the 15 tooth counter sprocket too, but I run a 13 or 14 on it most of the time, so its up in the 85 to 95 MPH.
Had my 86 Mustang up to 120 a few times and the motor and tranny have about 20MPH more in them but the suspension and brakes are out of there element at about 110 so I am much more scared to go that fast in the car than I am on the bike.
