HRC Throttle bodies

I have been after one of these for a while and do not appear to appear very often.

If you compare both the kit version, they are near identical. HRC describe the changes as supporting engine braking. It appears though that this is only supported by the HRC kit ECU. 

They say:

Replace the throttle body with the racing kit. 

NOTE: • The 2008 CBR1000RR is equipped with IACV (Idle Air Control Valve). Fundamentally IACV controls the air volume under the low engine speed range. But the throttle body of the racing kit, IACV controls the air volume under all engine speed range to optimize the throttle control. This intends to reduce the engine brake feeling under high engine speed. • Please use the HRC kit PGM-FI/IGN unit for the throttle body of the racing kit.

Along the way, found that there are two versions of the Throttle Bodies:

16400-MFL-R10 (08-09 model) GQ23DA MARKINGS 
16400-MFL-R11 (10-14 model) GQ23EA MARKINGS

The standard throttle body usually has a marking GQ23AA

Awesome eagle eye headlights

Well I doubt I will ever be brave enough to buy a conversion like this but saw these and the think they look amazing. I find that a great deal of headlight conversion often look tacky and dread it when I hear of angel or demon eyes. These however seem tasteful and do seem to suit the lines of the bike.

New rear suspension link (AKA Dog Bone)

As a fan of making the CBR1000RR that little bit better, I stumbled across a shock linkage from Lee's Cycles.
The Honda CBR1000RR comes with a standard Shock linkage of 175mm. HRC provide these in different lengths (170mm-172mm) to change the handling of the bike.
The Lee's cycles link is 170mm long and is based on the HRC version at a fraction of the cost. 
HRC List 4 different links listed for the blade:
1) 52470-MFL-R10 CONN ROD ASSY., CUSHION R1 (Standard) 2) 52470-NLR-A20 CONN ROD ASSY., CUSHION (MEL) 166.2mm 3) 52470-NLR-A30 CONN ROD ASSY., CUSHION (P2) 178.8mm 4) 52470-NLR-A40 CONN ROD ASSY., CUSHION (P4) 170mm
In Brief, MEL is the most aggressive, P4 is less aggressive, P2 is quite flat and the unlisted is offers the characteristics of the P2 but adjusts ride height.
The idea in general gives better rear grip on the rear and raises the seat somewhat to transfer some weight to the front of the bike. 
Besides the obvious advantages to the handling 5mm means less material and a few…

Favourite Fireblade designs

Its always interesting to see other colour schemes for the fireblade from the usual Repsol design. 
Here are a few of my favourite colour schemes together.
