Hi there,

just looked on the acceptance papers of my bike and noticed that power is stated with 47kW whereas otherwise NC30´s are stated with 44kW. I`m just wondering if there are any differences in the engine or intake/exhaust system between the K and later (L, M, N) models as the carb jetting is also different (110 all around for K model and 115/118 respectively 120/122 for later models).

cheers

No engine differences, the main difference is carb main jets.

The 110 main jets of the K model are nearly too small on a stock bike, certainly too small if it even has just an aftermarket muffler.

There all 44kw (59hp)

Only the UK bike was 47kw (63hp)

Your papers are wrong, common thing with foreign ipmorts.

The K bike has a poorer suspension (rear shock and forks) than the later bikes which is the main difference.

@Cammo:
Rejetting is already on my todo-list for next winter. Maybe earlier if idle run doesn`t get better after the first rides.

@Neosophist:
Wrong papers, thats clearly the easiest explanation
So what`s the difference for the UK models? Can`t find anything besides also different jetting.

As above, if its too much to read the main points in a nutshell without being tenchical.

uk spec bulbs and additioanl wiring to cope
no speed limiter as its not uk law
changes to bodywork to accomodate uk indicator and numberplate specs
radiator type oil cooler (borrowed from the older nc24) (perhaps just a sellign point to compete with the kawasaki zxr400 which was also a uk model and had an oil cooler.. at least that is my theory)

quioted at 63hp as there is no 59hp limit like in Japan
