First off a big thanks to Blackbird (Geoff) for helping me out with this minor suspension tweak.
One of the downsides of modern bikes is that they are sometime a little neutral in terms of their stock setup, as they have to cater for a cross section of society (size weight, riding ability). Honda's CBR1100XX Super Blackbird is no exception. The steering on it can be described as very neutral. It turns into corners ok, but it does take a little more effort when you get happen accross a tight set of twisties. So I did some homework.
From trawling the tinternet I discovered that by placing a washer with a depth of between 6-12mm at the top of the rear shock the bike would steer quicker. John 'Jaws' (http://www.jaws-motorcycles.co.uk/) , a top man, sent me a 6mm washer from the UK. I then sought some further advice from Geoff who had done a similar mod to his bike, but he made his own washer, of sorts, from aircraft alloy. Geoff then very kindly made one for me and sent it overnight. The physics behind doing this is that it raises the back end of the bike, so slightly more weight is transferred to the front wheel. I opted for a 6mm (ish) ride height increase at the back.
I fitted it this evening and have not long come home from a test ride. The difference is amazing. The bike now turns in far faster and better IMO. A highly recommended 'tweak'.
Many thanks John and Geoff.
