These pictures compare the TRF 414M to the prototype
TRF 414X (with setting dishes). The similarities are obvious, but there
are a lot of differences (enumerated in detail on the opening page).
Of particular note are the slightly extended wheelbase on the TRF 414M
and the replacement of all the aluminum hubs with plastic.
The TA-04 chassis was released in 2000, the same
year as the TRF 414. Looking here at the special TA-04 TRF, the
shared design history with the TRF 414 is very obvious. They have
the same bulkhead, pulley, and belt layout and very similar suspension.
