| Jenks...Mr S has summed it up really.
To give you an idea, my 748 Bip was set up to 575 mm from the top of the wheel nut to the top mounting bolt.
The problem with this measurement method is that it is not really reproducable from one bike to another...the only way of doing this is with a RH Tool, which fits directly into the frame and gives a consistant datum for reading to be taken. Its also useful as all the figures you will see banded about by various teams/sources etc, will be quoting off the RH tool datum, and not from this bolt or that nut.
UPDATE: Due to the great response in this, I have made a few enquiries within my various contacts, and have a good lead on being able to produce a large batch of these, at approx the same cost as mentioned before, laser cut to the desired dimensions....just waiting for a firm quotation (which I will chase tommorrow) before comitting and placing an order.
I hope to have a definate answer within the next few days, with a view to having these ready for sale in the next 2-3 weeks.
Watch this space...as soon as I know you'll know.  |
