Just done a bit of research on spring rates for R6 shock... they seem like over kill for Haynes:

03/04 R6 shock is 9.85 kg/mm which converts to ~551lbs
05 R6 shock is 10.98 kg/mm which converts to ~614lbs

But you guys say there are people out there with this set up? What's the ride like? .... don't say 'stiff'

Is there any info re spec for shocks for some of the lighter bikes ?. Would the spring rates on these be more suitable?

Cheers

Adrian

Right well maybe the r1 shock is better suited to haynes then i got a figure from yamaha that gave 7.84 n/ mm maybe ill have to do a vid of the travel i think the front with a new mounting point will be fine with my heavy ish 2.0 ecotec and its box.

Only thing with using them then is the length about 12" eye to eye

SV650 shocks are cheap, soft, and plentiful.

Probably a bit on the long side though - I just happen to have one sitting under my desk at work and it's 13.5 inches between mounting points.

how would 13.5 be too long if people are buying 13" with 1" extensions?

I think it would be ok you might need to move the mounting bracket on the lower wishbone though.

My bad. For some reason I had it in my mind that the shock length was supposed to be about 9 or 10 inches
Must have been thinking of the compressed length...

The book is only a reccomendation its not gospel. But it does say " other shocks can be used but you may have to move the mounting positions"

This is Locost mentioned before - with R6 shocks
http://www.youtube.com/watch?v=odehGEqqo1k

But - it has different front suspension (shock angle) so... for Haynes Roadster maybe R6 aren't best choice.

I found spring rates for SV650 on other site:
1999 - 2002 SV650 and SV650S have 510 lbs/inch - 9.129 kg/mm shock spring.
2003 - 2008 SV650 and SV650S have 430 lbs/inch - 7.697 kg/mm shock spring.

I had a pair of 1999 SV650s a few years back (one for road and one for track )
I changed the shock on the track one as it was faaar too soft. Can't believe they made it even softer on later bikes!
