KTM 690 Duke R (2010 model) - MCN
Even though the bike tested was a pre-production unit – virtually finished bar the paintwork and decals – this bigger capacity 690 Duke is altogether a different machine than non-R model 690 Duke (654cc). The extra 36cc (KTM won’t confirm this figure until after official model launch, mid Nov ’09) of the new R-model with carbonfibre front mudguard and revised suspension makes the new Duke-R a sharp-looking back road scratcher.
