Quality Eibach shock springs in a range of spring rates to dial in your rear Showa suspension to suit your weight.
Note – Spring rates are a guide only and people should do their own research. Some like fast single track with little amount of gear ( yep that’s me ) while others may carry a large load for an outback crossing. Some may prefer a firmer setting while others still like a small amount of plushness. One thing is for sure these bikes were designed around their original light weight Japanese test riders twenty plus years ago and the bike built for enduro racing ( winning an Australian Enduro Championship ) using a small tank and carrying no gear. Yes these bikes make an excellent adventure bike and is a proven package with so many dirt bike hire companies. Again the bike is ideal for a lighter weight rider but if your adding a big tank, pannier racks or weigh in excess of 70 kg you HAVE to change the rear spring.
The DRZ400 runs an all too soft rear spring and sits down a little at the rear from the factory. Example at 70kg the front springs are fine for my weight but the rear too soft and is necessary for me to go up one size in the rear spring. The DRZ400E runs a 5.3 kg/mm, the S and SM a 5.5 kg/mm.
5.3 kg/mm is standard ideal for very few !!
5.5 kg/mm is ideal for riders and gear 60 to 90 kg.
5.7 kg/mm is ideal for riders and gear 80 to 100 kg.
5.9 kg/mm is ideal for riders and gear 90 to 120 kg.
6.1 kg/mm for any large lads or people carrying way too much for the poor little 400 !
NOTE – While we try to keep most size springs in stock this often hinges on the Importer, if we are out of a size please email as we may be able to get one in our regular overseas orders.
