New HRC Swingarm

I have managed to source a Genuine HRC Swingarm for my bike. As the photo shows it comes complete with 2 shock linkages which are: 
There are two types of HRC Swingarms made for the fireblade. The first is designed for WSB and endurance and has gucci quick release rear wheel nuts and this version. This version is the 2011 and is much stiffer than stock. This can be seen in the photo with the weld seem and additional bracing.
The other advantage is that the swingarm is longer than standard, This makes the wheelbase longer and improve the handling (not that it needs it!). The cosmetic improvement is the lifter fittings at the end of the swingarm to ease lifting. 
For me this swingarm will complement the bike perfectly. Every other HRC Swingarm has been black in colour but was not in keeping with the Repsol CBR1000RR theme. The other advantage is that this still has the brackets for a stock brake or my…

HRC Style endurance lifters

Little HRC brackets at the end of the swingarm should be something easy to find. Well believe me they are not! As luck would have it I managed to pick up a new unused set for the bike which are used on the padgetts and Honda Road Racing bikes. Its almost impossible to get these from Honda so are exact reproductions.The photo is from the old Swan Honda team bike (Which was formerly a HM Plant Honda 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…

Modified clutch cable

Since I bought the Brembo style clutch lever and Harris clip ons I was having trouble with the clutch cable. The HRC cable was too short and started splitting on the lever adjuster end. 

The standard cable works better but fouls the clock bracket and is still slightly too short. As a result feels slightly snatchy when pulled.

I contacted Venhill who kindly said they would make one to my specification but were charging by the hour. This seemed an expensive way forward for me.

I contacted Motionpro in the USA who make cables to OEM specification. As luck would have it, they can make custom cables too. I contacted them and told them of my problem . As a result, I have made it longer and an elbow that clears the clock bracket. It also was slightly more than a stock cable too.

It's not been fitted yet but looks promising.
