Two things wildly exaggerated by the owners, top speed and penis size.
Aw hell .... it ain't what you got, it's how you use it.

Is it possible that not everything is bigger in Texas? lolAw hell .... it ain't what you got, it's how you use it.
Haven't you heard of the Panhandle?Is it possible that not everything is bigger in Texas? lol
I was such a newbie in early 2000's I had no idea how upset the squids and some elites, would get, similar to Brit Iron owners/racers would later over Ms Peel performance. Ms Peel was ~ 15 mph faster top than my SV650, 70hp/365 lb which ran out of pull approaching 120 then needed down hill and many more seconds to reach 127ish on its modern electronic speedo. Torque gives the pull power to speed while hp determines how long-fast that pull lasts. Some the highest times in my life so broken heart never got chance to put on the Drouin with GPS video. So any suggestions on 18" & 19" tires that can sustain over 150 mph or not come apart around 175 topping out? Just guessing here from past experience and calculators.
Peel performed exactly as you'all have described various road race Nortons, too sluggish to try for 120 in short Ozark opens - until so frustrated before selling d/t better performing moderns - I removed 10 plate supertrap for 12 ga slug through megaphone end cap to change my mind on best tool to spank/surprise my self and others - just not on any forums of course. Peel was my first engine build attempt, so extra points against believing any claims of a beginner in open shed shop.
The strange thing is that the little 650ss went around Mira in 1962 at 119 best, 111 two way average .
Bruce Mainsmith was on board and he looks to be roughly 2x Norman White in size!

With a 200 lb rider and 33 psi inflation pressure the K81 4:10 x 19 on my 850 has a radius of 12-13/16" (diameter 25-5/8") when stationary.The Mk III manual lists the diameter of a K81 4:10 X 19 tire as 26.46". Could it grow to that size "loaded" at speed?

ok Hobot now I am really confused, you said that your Commando hit 135mph, I assumed you had the Drouin hooked up but now you say that you never had a chance to put it on
So my question is - given your Commando was a Combat, correct? and it was not running a blower, correct?
then how could it possibly have reached an incredible 135mph? Seriously I would like to know
I have owned six Commandos including a very modified Combat with two into one into two Dr Blair exhaust, lightened rockers
and with a 22 tooth front sprocket at sea level with me weighing all of 120 pounds I managed to be verified flat out at 117
SO please explain your 135mph? thank you
When I was racing my Atlas/Commando hybrid, according to my calculations, with a 21/42 primary ratio and a 21/42 rear ratio it should have been doing 132MPH at 7000rpm. I took it to the dyno several times and each time the road speed of the dyno matched my calculated road speed. Since I saw 7000rpm on the track I assume it must have been doing about 132MPH. The dyno showed 58 horsepower at the rear wheel.
I too concur as your calcs are spot on. An interesting aside to your gearing is that you ended up with an overall gear ratio of 4.00 (42/21 * 42/21 = 4.00) which is identical to a stock bike running a 23T countershaft (stock primary * final drive [57/26 * 42/23 = 4.00]). So give or take a mph or two, due to differences in tire rolling radius, you're spot on.When I was racing my Atlas/Commando hybrid, according to my calculations, with a 21/42 primary ratio and a 21/42 rear ratio it should have been doing 132MPH at 7000rpm.
