hi all,

im a proud owner of a FZR400 EXUP. and i love it. Just got myself some RST leathers too. just need to get some new boots and a black visor for my helmet.

stupid question

What is the EXUP?

is it a name that was added on to make it go faster?? lol or is it like a fuel injection system used in cars??

It's a valve in the exaust pipe which closes at lower revs to make more torque. It effectivley maks the exhaust pipe a smaller area.

Exhaust Ultimate Power Valve
