Hillclimb Springer Forks

In the late 1920’s and early 1930’s, the Race Department experimented with a "trailing link" fork design on factory hillclimb race bikes. This distinctive design was the inspiration behind these reproduction Hillclimb Springer forks.

  • The versions for Big Twins feature a fork stem that works with a centering collar (not icluded) 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.
  • The forks for 45”/750 cc models have a 7/8” fork stem and fit the stock neck bearings.
  • The leg tops accept the 36-up Springer inline handlebars.
  • Wheel trail equates that of standard Classic Springer forks.

The selection includes forks for stock or similar Springer drum brakes and forks for Custom disc brake systems. Length is measured from axle center line to seat of lower steering head bearing.

1.) The pivot point of the brake shackle on the backing plate or caliper bracket must not be positioned vertically above or in front of the wheel axle (driving direction). In this case the moving forces in your fork parallelogram will be reversed and the fork will rebound instead of being compressed when applying the brake. That will create very high forces to impact on your rigid fork leg with possible damage.

2.) Caliper bracket or drum brake backing plate must float on the wheel axle. If not, the fork will rebound as well when applying the brake. Result: see above.
Internal Threads on the Upper End of the Legs

Internal Threads on the Upper End of the Legs

For custom riser installation the fork legs have M20x1.5 internal threads at the upper end and accept riser adapter studs or plugs which are available separately; an extra added by the manufacturer which saves you a lot of work and axle grease.
Inline vs. Offset

Inline vs. Offset

Classic Springer Forks are produced for different frame rakes.

  • In the beginning, both the lateral 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 on the Big Twins had a more inclined steering neck. To achieve still the same fork angle, the steering stem was inclined to the rear by 3°. we call these forks -3° Offset, they were stock on 1946-1948 Big Twins.
  • When building a bike with extra long forks you will try to avoid the steering neck being placed so high and inclined that the bike is impossible 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 +3° Offset, according to their rake. This type of forks has never been used on stock bikes, but our 8” over and longer Springer forks are made this way.

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.
