This is an ultra-lightweight and compact battery box for the Suzuki DRZ 400 S, SM, and E model motorcycles. It's designed to fit the lithium-iron battery Shorai recommends for the DRZ 400, the LFX14A2-BS12 (210 CCA vs. ~70 CCA stock).

I definitely recommend this upgrade for the bike, in part for doubling the effective battery capacity and for the weight savings. It shaves roughly 6 lbs off the bike at one of the highest points on the chassis. The new battery makes up a good 5+ lbs of those weight savings and my battery box will save a few more ounces and eliminate the need to stuff the old battery box full of foam to secure the battery.

I could make the box a bit slimmer, but I felt the extra volume could help absorb any impacts (like rocks thrown up by the rear tire).

Unlike some of the other high-capacity modifications for the bike (using bigger lead-acid batteries), this setup creates more space for wide rear tires, not less.

If you like the design, please "like" the design and post pictures of your completed copy.


Printed in PLA on an Ultimaker at 200 microns fill and 100 microns skin with 20% infill. Walls are 1.2mm thick for added strength. Support for the overhangs is built into the model and just need to be snapped off when it's done. Make sure your travel speed is high enough to effectively bridge the gaps and watch the support structures, on one print the support structures didn't stick to the bed and toppled. they're a bit thicker now for extra stability.

Awesome! I will be printing this for my bike soon. Has yours held up on the trails/rough terrain? I am scared I will hit a big bump or jump and shear it off.

Hey Engrkris, this is an awesome use of the technology! I know the point is to share the file and diy but i'm new to this and only have access to a small cnc. Any chance you'd consider fabbing another for an avid bike with a DR-Z? Much Thanks.
