NSW Top Fork Clamps

Smart clamps for inline Springer forks which accept all common bottom-mount handlebars risers. They ask for special socket head riser bolts with smaller head diameter which enters the upper fork tubes when the clamp is installed.

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.

Cannonball I-Beam Springer Forks

Cannonball I-Beam Springer Forks

Once upon a time when there weren’t any custom parts you could buy from your local shop, the VL fork was a very popular item because it made your Knuckle or Panhead bobber different from the next guy’s scooter. Besides you gained half an inch of length compared to 1936-up Springer forks for improved ground clearance and a more stretched look. Now it’s time to revive those days of the golden 40’s and 50’s with the Cannonball version of H-D’s VL type fork.
Manufactured just like the original, which means I-beams and connecting braces are drop forged on a huge 10 meter forge hammer. This is the only procedure that guarantees these components stand up to the job.
The problems with installing the OEM fork were the large fork stem and the handlebar mounting so the Cannonball fork is modified here. It features a Ø1” 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 Big Twin Timken bearings without any modifications. The leg tops accept the 36-up Springer inline handlebars. This makes installation a snap compared to the original counterpart.
Approved for 4-speed Big Twins thru 1986. Length is measured from axle center line to seat of lower steering head bearing.

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.
