Featured Listing: Sorted Harley-Davidson XR750TT replica

9.13.2018: Now on eBay. Good luck to buyers and seller! -dc

Looking at strange beasts like the 2019 Harley-Davidson FXDR, you'd be forgiven for forgetting that Harley ever had anything to do with road racing. Or turns in general, for that matter. Years and brand image have done much to erase the memory of the 1972 Harley-Davidson XR750TT, an honest-to-God, race-winning Milwaukee steed based around the firm's venerated 750cc flat track engine.

Harley built about 10 black and orange, fully faired examples of the XR750TT in '72, and in Cal Rayborn's hands they had a bunch of success in international match racing, despite putting out south of 100 horsepower, with most relying on front drum (!) brakes. The Lord works in mysterious ways, we guess.

Today's listing is a package:  The first bike is a turn-key replica of Rayborn's mount, albeit with some poetic license taken to tame some of the sketchiness of the original. For one thing, the builder stuck on a proper dual-disc brake setup. It also rides on a monoshock C&J frame and wears suspension from Ohlins and Forcella Italia. Beyond that, though, the bike is true to its roots, with a 1993 XR750 mill swaddled in lovely, delicate reproduction bodywork.

The second part of the package is a rolling chassis that is a nearly perfect replica of Rayborn's mount. The seller had intended to swap in the engine from the first bike to make a fairly faithful replica.

From the seller:

Harley Davidson XR750 Road Racer, C&J Frame Mono Shock, XR750 engine from 1993, Forcella Italia fork, Ohlins shock, Wire Wheels, complete Body Kit incl. fairing, partly new painted, new windshield, very good condition, runs great, race ready. Harley Davidson XR750TT Replika rolling chassis, complete except engine, Forcella Italia fork, Koni shocks, complete body kit, front wire wheel 18" and 16", many parts....

The Roadracer has been built in the late 90ies, based on a C&J Flattrack frame and a factory original 1993 XR750 engine.

Road racing fork Forcella Italia, Shock is Ohlins, brakes are high quality racing stuff. Equipped with the complete XRTT bodywork and Wire Wheels. This bike was raced by the pre owner in the late 90ies to middle 2000s at GrabtheFlag races and similar events in Europe.

The engine has been recently redone by the last owner and runs very good. I bought this bike 2 years ago and  rode this bike in 2017 only one day at a small race track for practice.

Additional there is a complete XRTT Replika Chassis with bodywork, only missing the engine. This bike was equipped with a XR1000 engine and was also raced in the late 90ies to early 2000s at european classic racing events. Fork is Forcella Italia, shocks are Koni, 16" and 18" front wheel.

My intention was to put the XR750 engine in the XRTT Replika Chassis, and ending up with a fine XRTT Replika, and buy a 90ies Sportster or Buell Engine for the C&J- Chassis and having a cool and powerfull Race Bike for Classic Races.

I would prefer selling as a package, for € 29000 OBO

Bikes are located in Berlin/ Germany.

The bike is across the Atlantic in Germany, but is very much worth the effort to import and turn into a once-in-a-while track day mount. With a full extra chassis waiting in the wings, there's little excuse to let it sit.

Old School: 1972 Harley-Davidson XR750TT Road Race Replica

For Sale: 1972 Harley-Davidson XR750TT Road Race Replica

Here at RSBFS we generally stick with rare factory bikes; there are simply too many modified and hot-rodded machines out there to consider them all. Every once in a while we come across a custom build that is worthy of - or even better than - factory. This XR750TT replica build is clearly one of those cases. Even if you are not interested in the bike, check out the pics and enjoy the quality of this offering. You will not be disappointed.

Just because this mighty giant does not have factory paperwork does not mean it does not have real history. This very bike has been raced successfully in AHRMA and WERRA series, and has triumphed under the likes of none other than Jay Springsteen. If there is a guy that knows what a XR750 should feel like, I reckon that Jay is that man. Given that the bike looks killer, it is nice to know that it has the potential to run like it looks!

From the seller:
Here is one of the Hourglass Racing XR750TT racers that many of you have seen on the tracks over the years. It is, as all our race bikes are, in immaculate show winning condition. It is also ready for the track by adding oil and race gas. If you do a search on "Hourglass Racing" you will find a great deal of info on this bike.

In the last few years it has been raced in AHRMA and WERRA road races. The riders have included myself, Chuck Davis, Tim Joyce, and of course most famously three time AMA National Champion and Hall of Famer, Jay Springsteen. Every rider has won races on this bike, with multi-time AMRMA champion Tim Joyce and "Springer" being the most successful. It has also been ridden in practice and parade laps on tracks throughout the country by the following racers: Mert Lawill, Mark Brelsford, and most recently at Road Atlanta by Chris Carr. Several journalists have also ridden the bike for articles about what its like to race an XRTT.

The bike was NOT born at Harley Davidson. It was assembled using parts and pieces, bought, found, and fabricated by many friends who were interested in seeing one of these bikes compete once again on American race tracks. The bike was built in the Hourglass Racing shop, and always maintained by us. The XR750 engine was bought new in boxes from Harley, and built by Carl Patrick in Ohio. Carl has always done our engines, and in our opinion, there's no one better anywhere with an XR engine. This engine has done a practice session at Barber but no races.

This is a race ready showpiece that can win on the track or in any show. To build a racer of this quality would cost in excess of 70K not including your time. We have built three of these racers over the years, and until now, never sold one. If you want to own a piece of art, that you can win on the track or at a show, this is your bike. To verify this info do an internet search on Hourglass Racing, XR750TT, and/or Springsteen.

Springer can pretty much win major events riding a moped held together with duct tape and zip ties, but his history on this bike must have an impact on the collectability and indication of performance of this amazing build. This looks to be choc-a-bloc with top notch componentry, and the fit and finish look far beyond that of the usual historic race bike.

All of this quality, performance and history does not come cheap - but then a base XR750 is a pricey foundation to start with. This auction is going on right now, and the seller has set a BIN of $45,000. I would think it would be very difficult to source all the parts at that sum, much less put it together into a working, effective racer. Throw in the documented history of riders, and you have a very complete package for vintage racing and collection at a relative bargain.

Here is a great video of Jay Springsteen racing against the late Gary Nixon. Jay is astride an Hourglass Racing HD (it might be this very bike), with Gary seated on a Triumph 750. Some great stuff from those legends.
