KLE650 FFF ABS. In contrast to the minimalist, non-ABS ER-6f in fourth place, just one place higher in the list – and with one more registration – is a machine from the opposite end of that range, the Versys 650.

The most expensive model in Kawasaki's 650cc parallel twin family, it only comes with ABS, and at £6749 it's £1350 more than the entry-level ER-6n model. And yet it's the best-selling variant of that entire line.

ER650 EFF. As the name hints, this is the basic, naked ER-6n, with no anti-lock brakes (the ER650 FFF ABS version comes in 24th on the list, with only 48 registered in the first 6 months of the year).

It's an example where, despite the fact that many riders now accept anti-lock with open arms, more seem to have been happy to save the £400 difference in price and accept the non-ABS model. Kawasaki's website now lists the more expensive ABS-equipped model for 2016, though.

ZX1400 FFF ABS. Just one more registration for the base version of the ZZR1400 puts it a place ahead of the ‘Performance Sport' model.

Combined, the sales figures for the two near-identical machines would be enough for third place in the list.
