The paint job on the tank tells you what you need to know – this interesting custom pairs a British frame with a Japanese engine…plus a whole bunch of other goodies!
Highlights of the work include a rebuilt engine bored out to 1,100cc with performance cams, jetted carbs, electronic ignition, and heavy duty alternator. It’s also got a Suzuki GSX-R front when, Ohlins rear shock, and a 6-into-1 exhaust. Additional details are available in this profile on Dennis Kirk, including an estimate in 2018 that the seller spent about $25k to put this together.
The seller states that Spondon only made about 12 frames for the CBX. Here’s your chance at one! Find this CBX for sale in Arroyo Grande, California for $40,000 or best offer here on Facebook Marketplace (you have to be a member of the Vintage Japanese Motorcycles for Sale group to see it, though).
