Lower bars and my bad back are going to knock the new cbr off my shortlist.

clip-ons are now below top triple, fork is shorter similar to cb500F .Swingarm has changed to accommodate a better axel adj system.

Thanks for sharing! The new dash looks interesting. I hope Honda keeps iterating and refining the CB500 series. When I started riding all the 500cc bikes were old stale designs that none of the manufacturers bothered keeping competitive and I jumped right past them when I thought I'd outgrown my first bike (a 2003 Ninja 250). I'm pleased to see so many fresh designs are available in the 250-500cc range nowadays.

A few further details.
All three of the 500 family gets the slipper clutch and the revised rear swingarm which does not seem to get mentioning.
Changes ro the swingarm mean much better chain andjusters (I have made up some new cursewords reinstalling the rear wheel until I've bought aftermarket swingarm endcaps which are stasing im place) and a different suspension linkage mechanism. This later one seems to be similar to the one used on the NC750 series.

Very good points. Seems like a significant upgrade.

I found this description of the "slipper clutch" on Sport Rider magazine:


The main benefit of a slipper or back-torque-limiting clutch is that it reduces the effect of engine braking on the rear wheel under deceleration. When you close the throttle on your bike, the rear wheel tries to turn the engine rather than the other way around, resulting in a sometimes considerable braking force. Four-stroke engines typically have more engine braking than two-strokes, larger engines more than smaller, and big twins are usually the worst. Excessive engine braking can cause the rear wheel to skid and can even effect the rear suspension action, causing wheel hop or instability. Some riders also tend to over-rev the engine on downshifts, and a slipper clutch can help prevent this from happening.

Honda introduced slipper clutches on its four-stroke racebikes during the ’80s, including the NR500 and FWS1000, and production slipper clutches first appeared on Honda’s Sabre, Magna, and Interceptor V-4 models. This setup used a one-way bearing to allow half the clutch plates to freewheel under deceleration. It was quickly replaced by the ramp-type unit as more manufacturers adopted slipper clutches, and this is the style used in most sportbikes today. Here, the inner clutch hub is made in two pieces with a set of ramps between them. On deceleration, the rear wheel tries to turn one piece of the hub faster than the other, which is being slowed by the engine, and the ramps force the hub apart, separating the clutch pack and allowing a certain amount of slip. Once the clutch starts to slip, the force on the ramps is reduced and the plates close up, introducing a certain amount of equilibrium into the system.​

looks like the rear suspension is completely changed.they have gone away from the pro-link to a twin dog bone very similar to the ninja 400.looks like the shock is mounted up side down too.

This could be my next bike if the US version looks like this: 2019 CB500F in red.

In fact it is the same type of system like on the nc700 and 750, I believe it's called Unit Pro-link.

New "marketing material" says that the 2019 engine has better torque curve and should rev better? New balancing shaft design, new exhaust... What about cams? Maybe changes in ECU maps? For that somebody just needs to read out the flash and make comparision.

If the balancing shaft is better, is it a full engine disassemble / assemble to replace? If so, not worth doing...

When are they going to test this new R on the track?
I'm looking forward to some test magazine showing us in detail.
To my knowledge first production bikes are expected in January, end of February - at least here in Europe. Which is sad as it is the coldest time of the year.

I might have not paid full attention, but I don't remember reading about new balancing shafts. Any case changing those is a major job, means complete engine disassembly - not to mention that balancer shafts have to work with the crank counterweights so if one is changed my assumption that the other did too. A lot more feasible to sell the current bike and buy a new one.

Cam timing and lift has changed. Material explicitly says that "valve lift increased to 7.8mm from 7.3" and from my measurements it has to be the intake as exhaust has lower lift. It also says that cam tiking has changed by "advancing valve closing by 5degrees" which is bullcrap as it stays it can be shorter duartion cam as well as advancing the same profile by 5deg. Can't say exactly until I get a new cam in my hands.
Ecu programming surely had changed. The bike has new exhaust (not only the silencer, but longer and different runners as well as different looking cat), different intake as per materoal and different cams. Timings and fueling should be different.
If anyone is willing to read their flashes I'm more than happy to compare those.

Looks like the exhaust could be more free flowing. Like the look of that fairing. Swing arm looks more user friendly maybe. Still looks steel box style.

according to Total Motorcycle.Com the "rigid box-section steel swingarm with new pressed-steel chain-adjustment end pieces" connects a new single-tube shock absorber.the old shock was double tube.

""""" Double tube more expensive to manufacture and tend to be stiff. Single tube can give a smoother ride, so the ride with the new shock will be smoother. They are slowly tweeking the 500 line into a very well sorted motorcycle. Honda's been good with this on models that run for awhile. For example the last of the 750 four more refined then the first couple years.
