Anyone have any experience of these?

I don't think I can quite stretch my budget to a Nitron

speek to the guys at jap4performance, thay sell them and nitron.
plus they know there 400's

Will do Mo, thanks.

bought one of ebay a couple of years ago with intention of fitting on a 99 blade looked a well made bit of kit with one damping adjuster rebound/compression combined sold it again on ebay as it was 25mm longer than the standard showa unit on the bike, cannot comment on its ability but was impressed with the build quallity of it at the time believe they are manufactured in france a french hagon if you like.

Nice one Dave,
I was debating whether to go for a Nitron or to give one of these a go, I reckon I'll have a punt on the EMC and use the other £100 on a RO fork upgrade

would ask them what distance between hole centres idealy it should be slightly longer than the standard showa unit maybe 5 to 10 mm longer if its not height adjustable ? sure somebody here could advise you of that . +1 to ricks kit done that myself well worth the money
