This diagram shows how the twin-tube technology works by allowing the oil to flow through the damping valves in only one direction.
The 2012 CBR1000RR has bowed to styling trends and sports a new LCD dash bristling with the usual functions.
In addition to the white/red/blue 20th Anniversary edition, the CBR1000RR will also be available in red/black and all black versions.
Honda released photos and information on its new 2012 CBR1000RR flagship literbike, with suspension and other minor tweaks heading the list of changes. While some details on the changes were provided, most of the Honda’s new features were already leaked by last month by a Hong Kong distributor who posted numerous photos and videos of the bike on his facebook page, much to the chagrin of Honda execs worldwide.
Heading the list the upgrades to the 2012 CBR are a Showa BPF (Big Piston Fork) that has seen positive results on both Kawasaki and Suzuki sportbikes, plus a new “Balance Free” Showa shock out back that basically uses the twin-tube technology found on Öhlins’ TTX shocks that are now practically de riguer on all racing machinery around the world. In order to reduce the massive pressure fluctuations on each side of a conventional shock’s valve damping stacks caused by the constant reversal of fluid movement during compression and rebound strokes (which results in cavitation, causing very inconsistent damping characteristics), the twin-tube technology features a double wall in the shock body that allows the oil to flow in only one direction through the valve damping stacks, which are separated from each other instead of basically using the same orifice on the shock piston as in a conventional shock.
A new LCD dash replaces the previous analog tach/LCD panel display, with the new setup featuring the usual bar-graph tachometer, along with the usual digital speedometer, clock, odometer/tripmeter, gear indicator, and temperature displays. The dash also features a lap timer, trip and fuel consumption computer, a “five-level customizable shift indicator” that presumably uses the five LEDs on the top right edge of the dash, and peak rpm memory function.
New 12-spoke cast aluminum wheels are most likely lighter, and the front fairing has been subtly changed, with reshaped ram-air ducts bracketing the headlight, and a “layered” fairing design that uses an inner cowl for strength that is claimed to reduce weight.
Available colors will be all-black, red/black, and a 20th Anniversary white/red/blue version. As before, a Combined ABS version will also be available, with the standard CBR1000RR retailing at $13,800, and the C-ABS version at $14,800. Deliveries to dealer is set for December 2011.
