DRZ sub-frame strength.

Recommended Posts

Whats upTT! I am brand new to this forum!

Wondering if you guys could pas a litle info my way?

I was just wondering if anyone has loaded up there drz for a long haul?

and if so have they or anyone else heard of the weight of a rider and lugage casuing the subfame to fail?

Thinking of doing a trip and would be packing some luggage (nothing major).

I herd stories and seen pics of klr and ktm 640 adventures loaded in the midle of nowehere with a carcked sub-subframes from the weight of the luggage.

That would suck1

anyone have anything to add on this?.....

Thanks.

Good question. Currently I am searching for racks to bolt to the subframe of my 03 drz400s, or I may even fab some up. Looking at the thing, it is apparent that geometry plays a crucial role... the closer to the front, the greater the load-bearing ability. Stick a big load (so to speak) up and to the rear, problems are sure to follow . . .my thought is to distribute the load as low and as forward as possible.

I've mounted a giant milk crate (about 3 times as big as usuall size) directly to the rear subframe, with 3 days worth of camping gear including tent, 5 liter gas tank and 6 liters of water. Whole thing probably weighed around 50-60 lbs. Crashed a whole bunch of times with it too, and the subframe doesn't show any signs of giving it up.

I'd hope Suzuki designed it to take a passanger that is least 170lb in weight, so it should be ok.

Funny thing is, while riding I can't even tell all the junk is back there. Picking it up is another matter though.

Thanks for the info!

drjack that was a good link, anyone looking for luggage should chekc it out.

I guess if the sub-frame is built for another person it shouldl be all right!

So looks like I wont have to get a replica built of chromoly

Sub frames are pretty strong. I would recommend using Happy Trails system. Did me well on my trip thru Siberia and Mongolia. See attached photos

Additionally I might consider beefing up the sub frame bolts with a high tension bolt of extra length, and using a lock nut on the inside of the frame.

Mauidrz,

looks like the sub-frame will hold up! good idea with the bolts.

Looks like you had quite the trip!

I guess you are the guy to talk to regarding "Adventurizing" a DRZ!

Anything you learn about the bike on your trip? things that worked? things that didn't? things you added? things to up grade?

Thanks for the info!
