Honda NS 125F SPECIFICATIONS, PRICE & IMAGES
but also lasting: in fact, was produced
throughout 1987 with excellent business results and virtually no major
mechanical or cosmetic subject to change. Note the submission in 1986
perpetuated the color replication Rothmans colors of the bikes Freddy Spencer
(adopted on other models like the NS400R) and marketing in 1987 versions of “R”
and “RII”, with full fairing.
but certainly very pleasant: the windshield
and the front spoiler can integrate very well with the structure of the bike and
nice tank support beams on the beautiful square tube frame. In the best
tradition of Honda, the quality of the superstructure and ‘generally high and
with a painting from the point of view impeccable quality and the refined color
choices. The only sour note, it seems the apparent lack of attention to the
radiator and the black plastic insert at the top (right and left) of the frame
near the steering column which, unlike other competitors such as AS-R , were
left with no aerodynamic appendages that might have to go to integrate well with
the front spoiler. Note that these black plastic, hiding a small closet (left)
and the tank to the mixer (right). Very well done the codon and the seat (no
opening) and the two side panels that hide the battery, the expansion of the
cooling circuit (right side) and the air filter (left side). Toolbox is
protected by a small lock is always under the right side cover of the codon, but
on a more ‘arrettrata than the battery.
and of course to happiness: ATAC, or Automatically Controlled
Torque Amplification Chamber.
ATAC mythical: it is a lung in practice increases the volume of the exhaust system, thereby
firing up the midrange. After the revolution of the middle zone, about 7000 rpm,
the lung is closed by a valve and flue gas goes directly to the exhaust pipe,
thereby the power at high revs. A pair of gears driven by the crankshaft drives
a mechanism which controls a system of external levers that push or pull out in
the exhaust valve and then changing the volume of the exhaust system, as
described above. Surely this is a much more complicated system of pneumatic
control valve mounted sull’Aprilia RAVE AS-R, but then who expected less from
Honda?
