We call it 5TA. 5TA combines the advantages of a thru-axle solution with the ease of a traditional open drop out QR system. Instead of an open drop out we are now introducing a closed drop out that gets combined with a 5mm QR style axle that requires no specific hub.
The 490cc engine of the 5TA featured a much shorter stroke than the original Speed Twin and had unitized construction, with the transmission mainshaft, layshaft and gears carried in a cavity cast into the rear of the alloy engine crankcases.
