Practical Sportsbikes (UK) - - Special Build of the Year 2018 -

First work out what you’ve got; UK 4DX or Ja­panese -spec 3TJ? Or is it an SP ver­sion? Dif­fer­ences in­clude mph speedo, in­di­ca­tors, mir­rors and tail lights; SPS have fully ad­justable sus­pen­sion, c/r ’boxes and wilder cam tim­ing.

As with all EXUPS, the valve can seize, and it makes a big dif­fer­ence on the small mo­tor. Main­te­nance is es­sen­tial, and new bushes are no longer avail­able so re­pair is ex­pen­sive. Ex­haust head­ers and col­lec­tor box are prone to rot too.

Seized calipers (bare alu­minium, not an­odised) need reg­u­lar clean­ing to avoid seized pis­tons and warped discs (an old Yamaha weak­ness). This bike has EBC re­place­ment discs fit­ted – a very worth­while mod. .
