It’s quite easy to be torn between these two incredible machines, really — hence, the need for today’s article.
Honda CBR650R and CBR600RR Origins
Launched alongside the naked CB650F in 2014, the fully faired CBR650F initially offered robust four-cylinder middleweight performance, leaning towards the sporty side of ‘sports touring.’ In 2017, it received a power boost, enhanced styling emphasizing the engine, a Showa Dual Bending Valve front fork, and revised Nissin brake calipers. Fast forward to 2019, and the CBR650F was rebranded as the CBR650R, with its styling inspired by the previous year’s CBR1000RR Fireblade.
In contrast, Honda faced an eventful year in 2006 (after the inception of its RC211V-inspired CBR600RR). The bike’s 3rd year was filled with excitement, disruption, and a touch of ominous undertones. While the CBR series continued to undergo key changes that spelled evolution for Honda’s lineups, it was also the same year that Honda lost to Yamaha in European sales. Despite the challenges, the firm turned things around by refining the CBR600RR’s design and improving its functionality.
Improvements Post Debut
Honda CBR650R
Among the first noticeable improvements for this year was a significant upgrade in styling and aerodynamics. The CBR650R adopted a more aggressive and sporty design inspired by the CBR1000RR Fireblade, including dual LED headlights and a more compact, sharply styled fairing.
Honda engineers meticulously fine-tuned the 649cc, DOHC 16-valve engine to eliminate a torque dip @ 5,500 RPM — delivering 5% more power above the 10,000-RPM mark and extending the redline by 1,000 RPM. This also resulted in the engine offering higher revs and a smooth, linear torque delivery, with a distinctive engine note.
The cylinder head’s direct cam actuation, alongside modifications like a redesigned piston and optimized combustion chamber shape, enhanced the CBR650R’s engine performance. Moreover, asymmetric piston skirts and an advanced cylinder sleeve design minimized friction. New twin ram air ducts fed a greater volume of air to the airbox, while the exhaust system incorporated a larger bore tailpipe to improve gas flow and deliver the engine’s sound more directly to the rider.
An assist/slipper clutch is now incorporated into the motorbike’s many perks, making upshifts easier and managing rear-wheel lockup during rapid downshifts. Additionally, HSTC (Honda Selectable Torque Control) is introduced for rear-wheel traction management and can be adjusted or deactivated at the rider’s discretion.
The CBR650R frame was updated with lighter swingarm pivot plates, reducing its weight by 1.9 Kg and lending to a more responsive and balanced handling experience. The motorbike’s suspension system also included a new 41-mm Showa Separate Function Fork (SFF) USD fork, enhancing rider comfort and control and making the CBR650R more agile and maneuverable.
