The unmistakable look of the classic Springer fork for custom projects.
Length is measured from the axle centerline to the lower steering head bearing seat.
The fork stem is compatible with the centering collar (available separately) for 1936-up ball bearings. It also includes two Ø1” bearing seats, allowing the use of 1949-up tapered bearings without any modifications.
These forks are not drilled for the 1948-and-later steering head lock.
Although these custom Springer forks are designed for 1936–1957 rigid-frame Big Twins, they can also be installed on later frames as long as you use/install the appropriate matching frame head bearings.
Due to the trail geometry, versions with an additional length of 8 inches or more feature an adjusted positive rake offset of +3°.
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
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 Classic Springer forks.
