Overview[edit | edit source]
Honda CRM 250R
CRM250 Mk2 & 2.2 1991 - 1993 The MK2 &
Mk2.2 are the same bike in practice, and the MK2 was launched in 1991. This
model was a huge step up from the MK1 with all new frame and now wears large
upside down Showa forks. Oil is now held in the frame which is much larger
than the MK1 and stiffer too. This bike feels far more substantial than the
MK1 yet feels more nimble to ride. Power has also increased with the
redesigned engine and offers more tourqe than before.
The bike still had it's little quirks though and with a couple of design
flaws including the wheel bearing securing plate (Made from a soft alloy
which screw into the hub also made from soft alloy - Cue bad corrosion, and
a seized plate. But even still this bike is the most popular CRM250 and
holding it's own in the values game even when so old. Beware for balancer
shaft wear in the engine, if regular oil changes are not done done this
seems to be the first thing to fail resulting is a death rattle from the
engine that still runs with no problems.
The MK2.2 had few differences including foot pegs that were different and a
new set of graphics.
Prices vary between £700 for a rough looking H plate but useable bike to
£1500 for a very clean tidy example on a K plate with around 8000kms on the
clock.
