 When is a diff not a diff - When it's a Bevel box.  The shaft drive shaft is spins in line with the bike. This is no use whatsoever, because the wheel needs to spin at ninety degrees to the motion of the spinning drive shaft.  The bevel box contains a pair of gears that turn the spinning motion through 90 degrees to cause the wheel to rotate.  One gear,(The crown wheel) is much larger than the other (The pinion) hence the bevel box is quite large.  There are no chains involved.  The wheel fits into a splined hub that is part of the Crown Wheel assembly.  The Bevel box holds a quantity of gear oil to keep things running sweet.  This is where Allan's problem stemmed from.  Some kind soul had crossed threaded the oil filler so the oil couldn't be topped up or replaced.  Mr Honda had put the exhaust very close to the filler hence the exhaust had to be removed to get at and remove the cross threaded filler bolt.
