   Up front is a full width sand-cast magnesium hub and magnesium backing plate.  The brake pivot is hollowed out titanium.  The brake arm is cast aluminum.  The brake arm is an updated one that is about twice as long as the initial one.  This was for more leverage resulting in more braking power.  The fork sliders are hand machined from billet aluminum.  Front tire is the original Dunlop sports senior that was on the bike when Torsten raced it last.  Even the cable guide is hand made.

      

  After the inital rear hubs failed, this was the final updated hub.  It is sand cast magnesium and conical in design.  The rear sprocket is machined from aluminum and held in place with hand machined steel bolts.  This is the original Trelleborg rear tire that was used at the 1971 250 Swedish GP.  Exhaust stinger exits at the top shock mount.  Oh to hear that sound and smell the Castrol R.

      

  The rear shocks are the original machined Aluminum hard anodized Kayabas.  The red label is the original label that Identified the valving codes.  They weigh just over 3 pounds for the pair!  The rear backing plate is sand-cast magnesium and the brake pivot is hollowed out titanium.  Brake lever is cast aluminum and the brake arm is machined aluminum.  There is a special rear brake cable that goes all the way from the brake lever to the brake pedal on the other side of the bike.  This was made extra thick so there wouldn't be any binding.  Also with the motor being mounted too far to the rear, this not only hampered the weight distribution, but also made for a very short swing arm.  This resulted in too much rear wheel hop.  Torsten's extensive R&D work corrected this for the 1972 works bikes.

                                       

  Torsten used Husqvarna handlebars in 1971.  The front forks are completely hand made.  The damping qualities were not up to standard initially.  After Kayaba flew in two engineers to Sweden, and many laps and hours of testing, the fork performance was spot on.  The front number plate is signed by "Mister Motocross" Himself.

                                                                                                  The top triple clamp is sand-cast magnesium and the bottom is machined from billet aluminum.  Different off-sets were tested.  Hand machined pinch bolts hold the forks in place while titanium is used at the steering stem.  The steering stem itself is also titanium.

     

  While most works gas tanks are hand pound aluminum, a mold is often used for the shape.  This tank was hand pound with no mold.  It is a work of art.  I have five extra tanks for this bike and each one is distinctly different than the other.  It still has the original paint from 1971.  These bike have soul!

      

 The original Yamaha grips are still there.  The throttle housing is a works sand cast aluminum unit. The blue electrical tape and masking tape connected to the throttle housing have survived since 1971! (also note the photos below).  Lever covers are also the original ones.  Upon close inspection you can even see that the front brake lever still has the slight bend in it that it had in 1971.  It is very rare to find a historical works bike that is preserved in the original condition of the day.

   

                           August 15th 1971 the 250 Swedish GP and 34 years later in Lake Forest, Illinois.   Priceless!!!
