But then I think he moved onto a Harley which is basically a tractorI think of him every time I back my bike out the garage and think “ Who the f%#@k would jump one of these?”
Saw him interviewed and he reckoned the Harley didn’t fly straight like a Triumph - he put it down to the clutch/ primary being very heavy & onesided. One of his classic lines was “ I knew I couldn’t make the jump but you can’t tell 20,000 people to just go home..”But then I think he moved onto a Harley which is basically a tractor
Pretty certain the H-D XR750s he used were quite a bit lighter! With 80hp on tap, certainly a lot quicker than the GT/AE. Top racing examples of the early iron-engined models nudged close to 100hp.But then I think he moved onto a Harley which is basically a tractor

I’m going to take the front mudguard off mine- get the weight down to around 500lbs!
Don’t know when blip & brake came in, probably with the Supercross guys in the states tiding two strokes.Modern jumpers using acceleration and braking to control their bike's path through the air. Met one at a show who referred to Evel as a "dead sailor".
My first time on a full-on MX track was at the old Jillaby Park, north of Sydney, on a Yamaha XT 500 with its pathetic 100mm rear suspension travel. After a few laps to learn the track, I hit the big jump on the main straight at around 80kph in 4th gear and landed flat, not rear-wheel-first. I hit so hard it felt like my hips were driven into my knees. I rode straight off and had a nice long lie down in pain. How those professionals jumped those distances and speeds with buggar all suspension travel and on 200kg bikes was crazy, and every second time resulted in long Hospital stays. Just nuts. Around the time I had that, XT Supercross was the next big thing, so many ended up with really bad injuries; it took lots of training to even try a typical Supercross track, skills and bravery way beyond me.
"Neuroplasticity," is not why I took it. I did climb a ten-foot fence to get into a Band of Light concert, so perhaps some neuroplasticity was involved. We had tickets for the concert, so it didn't help my decision-making process.The young man we ran into explained that when learning a new trick, they'll drop acid -for the neuroplasticity? or just for fun!- and do the jump into a foam pit dozens of times; and that crashes in their world are nearly non-existent.

If you call the Harley a tractor, then you'd need to classify the GT/AE as a steam traction engine...

Iron head XR's were in the 82-83hp range at the rear wheel. The alloy XR's in the 90hp range and towards the end of the XR era in the 2000's there were quite a few that were in the 100hp range. A good friend of mine was there right from the beginning and has built and dyno'd many xr's. He used to road race his back in the 80's and 90's.Pretty certain the H-D XR750s he used were quite a bit lighter! With 80hp on tap, certainly a lot quicker than the GT/AE.
