BCS Plunger Sections
544 Series
Lower and lengthen your Triumph
while still retaining a few inches of suspension travel, using a BCS plunger
section or plunger frame.
These are very similar to those used by BSA and Indian in the good old days, and
to the custom "Santee Softail" or "Amen Saviour" of the '70s. Axle carriers and
springs are chrome plated, and require the use of the 37-2089 axle adjusters
used on virtually all pre-oil frame Triumph rear wheels. These plungers are
designed to be used with the pre-oil frame Triumph rear wheel setup, but we have
seen conical hub rear wheels used with a bit of work.

Don't forget: with any of our custom rear frame sections you will need a custom
oiltank, fender mounts, and and extended brakerod, chainguard, and chain, all
generally available through BCS.
Note:
Please bear in mind that all tail
sections and frames we sell for British bikes are manufactured with some offset
to reflect the run of the rear chain, and thus are not intended to be symmetric.
In addition, due to slight warpage caused by cooling after manufacture, long
storage, and shipping, it is not unheard of for frames or tail sections to
require some slight alignment during assembly of the motorcycle. As all of these
items are made of mild steel which is quite malleable, this should not be much
trouble to affect, and does not indicate a faulty frame or tail section, just
normal manufacturing tolerances for this type of product.
