Barely Legal Moto-Porn: 1972 Harley Davidson XR750 for Sale

1972 Harley Davidson XR750 R Side Front

We don’t normally get to feature Harley Davidsons on this site because The Motor Company really didn’t make many bikes you would normally categorize as “sport bikes,” and the ones they did build are extremely rare. Although the Harley Davidson XR750 was originally intended as a flat-track racer, today’s example has been reborn with roadgoing equipment and I’ve decided it qualifies, since it’s supposedly powered by an ex-racing engine and I bet it could would eat most of its roadgoing rivals from Triumph or Norton for lunch.

The race-ready XR750 is considered one of the most successful racing motorcycles ever, winning 29 of 37 AMA Grand National Titles between 1972 and 2008. Yeah, you read that correctly: the XR750 was competitive in flat-track racing for over 30 years. It was powered by a 748cc pushrod v-twin with aluminum heads from 1972 on that improved cooling, compared to the earlier iron heads. Certainly that engine featured primitive architecture, and yeah, it was only competitive considering the specific ruleset that governs flat-track racing. But let’s be real here: all racing is governed by rules that artificially limit development to help keep performance of competing machines somewhat comparable, so that in no way diminishes that impressive record of wins.

Today’s machine is claimed to have a genuine racing engine with some very impressive history slotted into the frame. Although it was originally a race-only machine, this XR750 has been fitted with lights and a license plate, meaning it might just be road-legal where you live…

From the original eBay listing: 1972 Harley Davidson XR750 for Sale

Surprisingly well preserved Harley XR750 flat track bike with 1972 engine.

Street legal in most states, and WITH TITLE! MATCHING NUMBERS on both engine and frame!

This particular bike’s engine is reported to have been ridden in 1972-73 by Cal Rayborn, Mert Lawwill and Scott Brelsford. Harley racing royalty then and now. Of all years of HARLEY XR750, 1972 is probably the hardest to find, since they were very popular, in short supply, and were either used up or supplanted by later year engines with more power.

This bike does not have an odometer or a speedometer, so I have no ideas how many miles it has run.

1972 Harley Davidson XR750 Rear Suspension

What kind of flat tracker has dual front brakes? Or any front brakes, for that matter?! Well whatever the engine and frame’s original provenance, they’re part of a bike with roadgoing intent now, and the stopping power afforded by those dual calipers will be much appreciated, considering the potential speed on tap.

The Buy It Now price is listed as $29,495.00 with very little time left on the auction. That’s a great deal of money for a motorcycle, but considering that XR750’s don’t usually offer you the opportunity to terrorize your neighborhood, it’s really like you’re getting two bikes in one!
