I'm about to stiffen up my springs to match my obesity, but that is far from easy.
The local Austrian suspension shop I'm in contact with has sent me the wrong spring
(30 mm longer than stock) and wrong fork springs (20 mm longer than stock).
So I did some reseach:
When I try to find a KYB shock spring they don't have one
that has the stock 240 mm free length, with an ID of 60mm : see page 175 in
With a lot of determination I cloud fit one of the 260mm springs.
Would have to fully back out the top spring seat for that.
Btw, above KYB catalog lists the 2012 WR450F fork as open cartridge, go figure.
the Eibach Catalogue at
suggests spring type 892 for the shock. However, 892 is 270mm long, exactly what the suspension
shop sent me at first attempt. 10mm longer than what one can squeeze onto the shock.
So, should any WR450F 2012+ rider happen to have his/her suspension off the bike please do measure
free length and ID and please post them here. I'm on the brink of suspecting a modified suspension in
my used 2012.
