Inline vs. Offset

Classic Springer Forks are produced for different frame rakes.

  • In the beginning, both the main tubes and the steering stem were in the same plane. This is called "inline". The rake is 0°. Of this type were all 45” Springer forks 1936-1957 and all Big Twin forks 1936-1945.
  • From 1946 onwards the Big Twins had the neck angle increased to 30°. To maintain fork inclination and ground clearance, the steering stem was tilted to the rear by 3°. We call these forks Offset -3°, they were stock on 1946-1948 Big Twins.
  • When building a bike with ≥+8” extra long forks you don’t want the steering neck so high and inclined that the bike is difficult to steer. Therefore such forks are manufactured with a positive rake, i.e. the steering stem is inclined to the front by 3°. We call these forks Offset +3°.

The sketch shows the placement of the lateral tubes and steering stem seen from the drivers place. Now it is clear, too, why there have to be three different types of top trees or handlebars for Classich Springer forks.

Classic Springer Forks

Classic Springer Forks

Complete and accurate reproduction of the classic H-D Springer fork as used by the factory on Big Twins 1936-49 and on 45” models from 1941–57. Manufactured just like back in the good old times, i.e. with forged legs and connecting components, which makes them equal to the original counterpart concerning stability and service life.
Use these top-quality forks as stock replacement for your restauration or as a part of your chopper or bobber project-bike.
  • All brackets for brake anchor, front fender and ride control are there and just like stock.
  • The dimensions of our standard forks are exactly the same as for the original Springer forks (48,5 cm = 19” from center of wheel axle to lower neck bearing seat).
  • W&W Springer forks for Big Twins are divided in “inline” (1936-45, rake = 0°) and “off-set” (1946-49, rake = -3°) groups and are designed to be installed on rigid frames with stock neck rake.
  • Big Twin versions feature a fork stem that works with the included centering collar for 1936-up ball bearings. Moreover the stem also features two Ø1” bearing seats for the use of 1949-up Timken bearings without any modifications. They are not drilled for the 1948→ steering head lock.
  • The forks for 45”/750 cc models have a 7/8” fork stem and fit the stock neck bearings.
  • The "Builder" versions come unassembled with bare rigid and spring forks, chrome or black springs and black rockers.

Length is measured from axle center line to seat of lower steering head bearing.

Cannonball Leaf Spring Forks

Cannonball Leaf Spring Forks

The retro custom bike builder scene sometimes likes to experiment with parts of different brands on the same bike project. For example Indian parts are installed on Harleys and vice versa, with often astonishing results. Among the most positive mergings was the combination of an Indian leaf-spring fork with an H-D Big Twin rigid frame. This type of fork was used by the Wigwam in the 1910 to 1945 period which proves that this was a very successful suspension principle with excellent driving chracteristics.
Of course, the stock item doesn´t fit a Harley frame without major alterations, so W&W decided to produce its own version which allows such an installation without many difficulties. But, of course, not another quick and dirty copy with ugly welding seams and wrong rocker geometry. The Cannonball fork is a professionaly made part with a design as close as possible to its original pattern, manufactured by expert craftsmen in Italy. The first complete prototype was rigorously tested during W&W’s winter tour in Northern Canada and after that sent to the German TUV for a certificate of stability (included). Both tests were passed without any flaws. After that production started.
All test rides were performed with a rigid frame, 30° neck chassis, with which both handling and braking characteristics proved well balanced and stable.
The Cannonball leaf spring fork features a fork stem with two Ø1” bearing seats for the use of 1949-up Timken bearings and leg tops to accept the 36-up Springer handlebars (inline). A horizontal bracket to mount the headlamp is also there. The fork is wide enough to accept disc brake or drum brake systems. Rockers are drilled for 17 mm axles but can be enlarged to 19 mm. Neither axle, spacers nor brake are included and must be purchased or fabricated separately. Each fork is shipped preassembled to insure proper function and fitment, however, all components are bare and require painting or plating.
