sp engine/ box

[Jackh2]

How do I tell if my bike has a sp box? I've been told the lumps replaced with a sp lump, I know gear ratios will be different also heard that they run slipper clutches? Truth or bull? , if it is a slipper clutch will there be any visual difference when looking in from the clutch cover? Thanks in advance

The slipper clutch on the zxr is SBATL something like back axle torque limiter, sp gearbox runs a 16 tooth front sprocket, you can check the engine number on here aswell

I've got SP gearboxes in two engines....................in both cases the engine number will reveal that they are NOT SP


just saying

Could also get an sp engine with a standard gearbox
