I'm 6'3" 220 lbs Hub, so I dwarf all my bikes except for the ZX-14 which may be the reason I get along with that machine so well.
Ape is a full 1100 and tuned, so has about 70 BHP on the Ducati 959 at the back tire, Ape turns in super quick but the Ducati feels more stable but slightly slower to turn in.
On a twisty back road, I can relax more with the Ducati, the Ape makes a long straight seem short, things happen a lot quicker.
Ape would be perfect for a mega-track like COTA, not so much on our local track, G2 Motorsports Park, which is pretty tight.
I agree fast road and track are different like the Isle of Man TT is different from short circuit racing, two different animals and fast on one does not automatically make you fast on the other but there is some overlap.
I road ride with local racers all the time, novice to intermediates cannot keep up, I feel comfortable running at the Expert roadracers pace on back roads.
One of the problems with track is how many days a year can you ride and the cost? It's very expensive and only a few track events per year at G2.
I live literally three minutes from awesome back roads here in North Texas and my work from home job allows me to ride almost every day, year around, I'd guess 250 days out of the year conservatively. It costs me about $6 worth of gas to have an hours worth of back road fun.
Here's me on the APE, I look like a monkey riding a football, Ape is a 600 size machine packing a whole lot of power!
