I have run in the above series with a Buell Blast for 3 years, I usually average 5 to 20 seconds off the pace on the Blast. Now that I have upgraded to the Thruxton I should be doing better. I was just seeing if there was a belly pan pre-made. If not I will just get out the fiberglass and make one.
Have a great day
