XR 750 .

Just watched them both. Very interesting & thanks for posting.

Last rider to win a National event on an XR 750

I met a guy who had an XR750 road racer at the Broadford Bonanza a few years ago. He told me he had built it from bits he bought off the web, when I asked him where he got the cylinder heads.

Tripp Nobles still competes in AHRMA events on this XR750RR.

Watching him and Stan Keyes go at it at Little Tally last fall was a treat.

Beautiful bike!

YES IT IS!!!!

I was riding my 500cc Triton in practice at Calder raceway. Don Emde was riding an XR750 which seemed to be quite quick. It destroyed the timing side main bearing, so did not get to race against the fast guys on the Sunday. When I was building the Seeley, I thought of that motor. The bearing problem was fixed in later Sportster motors, and there is a 5 speed gear cluster for them. The only problem is the standard ratios are stupid. There was a guy with an XR750 at Broadford a few years ago. It was beautiful. He said he had built it from parts he had bought off the web.
There would be a very good aspect of racing an XR750 - I like to feel the hairs growing on my chest.

Some one is repoping XR750 engines maybe Harley. You must assemble it but the info I got from a Harley builder they take a lot of work to make them correct. Our local 1/8 mile drag track discontinued the pushrod class due to the cost of building a Harleys!

Danno I am always amazed by photos of this bike they make it looks so big/ bulky.
In reality it's not. My friend built a replica for parading & its stunning.

Some things are worth doing, simply because they are good things to do. When I built my Seeley 850, it was not built to suit a particular race class. It just happens to be similar to the 750cc Gus Kuhn Seeley Commandos. I built the bike, but never really believed in it. It was just a good thing to build. An XR750 Harley would be a good bikwe to build. I would worry about racing it after I had built it. Of all the bikes which have been built for historic racing in Australia, very few have any sort of authenticity. The XR750 was a real race bike, not some imitation which has been dreamed up in somebody's head.
Those 1100cc CB750 Hondas I sometimes race against are good race bikes and they fit within the historic racing rules. To me, they have no value. Nothing like that existed in the 1960 or 1970s. THe biggest CB750 was usually 830cc.
If I had an XR750 racer, I would love racing it, regardless of where I finished. Winning races is not the be-all and end-all. When I saw Don Emde on the XR750, I thought I would love to own one of those. It was not much of a success as a race bike, but it looked great and did not go too bad. It is like a Rob Nerth Rocket 3, slower but gives you a really great buzz. It is like going on holiday, sometimes the journey is better than the destination.

I built a very fast methanol-fuelled T250 Suzuki. The guy I sold it to won 28 races and 5 championships with it. I had also won a race with it. It did everything perfectly, but it was simply disgusting to ride in a race. It was a lot cheaper to build than an XR750 Harley or a Seeley Commando. Sometimes it is possible to defeat yourself with your own mindset. The XR750TT road racer was never fully developed. You would not know it's capabilities until you actually raced and improved it. With my Seeley 850, I always believed it was bullshit, but it turned out that it was not

I have a friend who is into Harleys. I once asked him which frame was used for the XR750 road racer. He pointed to a 1200cc Harley and said 'it was that frame'. It looked very spindly to me. But a Harley Sportster is not super expensive in Australia. They are not so popular. If you have got the frame and the engine, you have the bike. The rest is not difficult.

Sportsters are a good choice for abuse! 91-98 five speeds are the best. Basic bike here is $3000-$5500. LOTS of performance parts! 883cc to 1600cc depending what you want and how deep your pockets are. Buell heads are a good start! Don't know prices now were $145 @ head now Harley ported heads are around $550 each. Transmission take lots of abuse, straight cut gears, some real noisy but don't break!

99 cu in 130HP surprises' the shit out of rice burners! (in a straight line)

Didnt know these existed untill two minutes ago .



1961 XLR 883 . I guess thats silver paint , not aluminum , for the top end . or were they a best kept secret .

If you cant join em , Beat Em .



Looks like theyre not taking Indians current effort lying down . Tho wonder if a T100 500 at half the weight might not be a bad idea .



Cause theres always this , if someone pulled their finger out .

To old for me to know! Looks suspicious the way the jugs fit to the case. As far as I know it should be all case iron but older then my knowledge

IF IT AINT THERE IT DONT WEIGH NUFFIN >

O.K. I was actually looking for THIS .

Think the dropped valve syndroms as you dont run em at 8000 rpm , so theres only half the oil , for those clearances .

Ora realone .






AS it weighs 350 Lb , everythingelse isstill obsolete ! .
