DR-Z400 with kickstart kit -- does it run without battery?
 

BTW, it's completely insane that these bikes don't come with kick backup!

The kit is £250 quid too...

Suzuki part number: 26300-29812

Says its only for the E model but it DOES fit the S models.

Theres a good fitting guide on ADVrider.

I bought mine (DRZ-400E DR-Z400 BACK UP kick start kit)
for $226.00 including shipping from the states (Mt. Pleasant, Utah, Suzuki, Kawasaki, Motorcycle, ATV, Scooter, Utility-Vehicle, Dealer, Used, Parts, Accessories, Apparel) The guy I dealt with was Shane Greene.
Took a couple of hours to fit and comes with everything you need. I didn't use the decompressor lever that came with it because it looked pants. I fitted a perch and levers of Honda CRF 450. (nice and tidy)
It's saved my bacon a few times and I often routinely start with the kick to preserve the battery.
