Seat/fuel tank adjustment (Monoposto)
On the single-seater version, the complete seat-fuel tank-
tail guard assembly can be adjusted by sliding forward
and rearward along rear subframe (1) axis.
This provides a 20-mm adjustment range for the seat (2)
to meet rider's preferences.
Adjust as follows:
Release and remove the side screws (3) and remove the
side grab handles (4).
Slacken the screws (5) and move the seat-fuel tank
assembly forward or rearward.
The three holes (6) in the subframe (1) allow three
different positions.
A stud (7) fixed in the centre of the tail guard slides in a
slot (8) fitted with an "H" rubber (9).
Match the seat hole with the subframe hole that
determines the desired seat position.
Tighten the screws (3) to the specified torque.
Position the side grab handles and tighten the side
screws (1) to the specified torque.
