The weight becomes an issue off-road, they called the CL450 the “Scrambler” but I don’t think anyone seriously scrambled with them. However in the States there are lots of unpaved roads where the off-road setup makes more sense. From experience the setup hides the weight, the bike feels relatively small and chuckable. It doesn’t feel super powerful (though I’m used to much bigger capacity bikes) but fine for the runabout I use mine as.
The eBay bike went for £2,650, more than my project bike cost at £2,200, but vgc exhaust and more complete than mine was. It does seem to need a new front mudguard, some of the silver looks to be paint, not chrome and they’re not cheap or easy to find (although James has one).
