i have the i900 with remote, the remote is ace and replaces a clamp on your odi lock on grips.a nice touch.
only difference with the 950 and 900 is that the 950 has a lighter clamp assembly and can be used a bit more in line, the 900 is mmore lay back.
a lot os our french customers use the i900 and nico voulioz had one on his bike. all of them rate it and have no problems.
one had a joplin that was leaking a lot of oil.
I think its down to how well the item can cope with UK mud…
I am happy with mine and have had no problems after 4 months..
