This wonderful Cal Bike was first set up as a marvelous representation of Calvin Rayborn's XRTT that he used in the 1973 Imola 200 Races in Italy.  The motor is documented with a factory motor test card showing this motor was used for Cal in this race.  Includes other documentation of history of the motor as far back as traceable.

This bike is now on commission from Scott Guthrie and has been set up as 1972 Cal Rayborn XRTT with Fontana Brake with Cal's #14.  Since this arrangement with Scott, the tail section has been autographed by Calvin Rayborn III (Cal Jr's Son), Bill Werner and Babe DeMay.

This bike was originally in built for John Steel's personal collection, taking over 3 years for the build to be completed.

The chassis includes many rare and obsolete NOS parts and the other parts are new.   Including other parts on the chassis as used by Cal Rayborn.

The XRTT has a short circuit fairing with the 4-Leading Shoe Fontana and now has the option of the dual disc set up.

It comes with rare era correct Avon Grand Prix NOS tires, made in England.


The sale will include a factory style stand, a complete packet of information ever written on the XRTT and XR motor and information and photos of Cal Rayborn.  It will also include sales brochures  hop-up and starting information, owners manuals and parts book.

NOS Tires

Fontana Four Leading Shoe

CEV Kill Button

Factory Work Card with Documented Motor History

The motor was used as a backup motor for the 1973 Daytona race.

The top factory riders for that race were; Mark Brelsford #1, Scott Brelsford, Mert Lawwill, Bart Markel, Cal Rayborn, Dave Sehl & Rex Beauchamp.  Renzo Pasolini was an exchange rider. 


The Daytona race in 1973 was one of the most memorable races in XRTT racing history.  Mark Brelsford hit another rider (Larry Darr) that had broken down.  Brelsford’s motorcycle burst into flames with him on it causing him to crash.

A photo of the fiery crash captured by Daytona Beach News Journal became famous.  Cal Rayborn was also injured in this race.  This was his last race at Daytona.

Larry Darr's 

1972  XRTT 750

The bike that Mark Brelsford 

crashed into 

An Amazing Find For Any Collector


Until now, the frame from the Larry Darr XRTT that was also involved in the crash is one of the first two original XRTT frames that we at Hi-Speed have ever seen and are aware of to exist.  Knowing that this bike made headlines around the world at the 1973 Daytona 200 is amazing.

The 1972 XRTT involved in the fire crash has been restored with the very rare, original factory frame, original specialty four-leading shoe Fontana, rare racing Goodyear inner tube and all other parts.

This bike was dealer maintained and owned.  

This extremely rare bike includes original AMA News magazine and Cycle Guide magazines with the 1973 Daytona 200 Crash of Mark Brelsford  on the cover where he hits this bike of Larry Darr's.   Also includes Autorgraphs and history of the bike and rider (Larry Darr).  Larry has told his story of his racing career and the point of his near fatal crash.  

This sale will also include brochures, enthusiasts, other literature, Brelsfords history and tuner Babe DeMay autographs.  

This is a one of a kind!    $119,950

Hourglass Racing XRTT For Sale

Ridden by

Jay Springsteen

As many of you know Hourglass Racing started road racing XRTT's in the early nineties. During that time Hourglass Racing has won many races in the Vintage classes of AHRMA and WERRA.  They usually had three bikes at the races, with one held in reserve as a spare bike for their most famous rider, Jay Springsteen, or as a parts source. This is that spare bike. It was never raced, however, it is fully functional and can be ridden. The bike has a fresh, never raced, Carl Patrick built engine. If it is to be raced, it will need the suspension tuned for the weight of the new owner. Other than that it is race ready.  Please call for more details & price.  440-247-6021
