Eamon had one of these:

It featured in MCN when they did a “then vs now” article and put it up against a CBR600RR (!)

The old CBX did quite well, putting up:

Standing 1/4 mile:
CBX: 14.02 seconds @ 96.4 mph
CBR: 11.48 seconds @ 126.8 mph

Top Speed:
CBX: 117.35 mph
CBR: 160.04 mph

On the dyno:
CBX: 53.02 bhp, 31.70 ftlb
CBR: 108.07 bhp, 44.59 ftlb

The bike is in Canterbury now and still ridden regularly.

MCN Verdict (Roland Brown):
“The CBX, outdated, out-moded and out-performed or not had two massive things going for it even by modern standards: it was impressively comfortable and roomy (especially for pillions) and, better yet, it had bags of character. And maybe that’s why today’s bikers, more than ever, often have a superb modern bike – but also either own or lust after a classic from their youth too.”

That’s us then…   🙂
