Suzuki DRZ400SM fork yokes

10 posts in this topic

Suzuki 2006  DRZ400SM  VIN#JS1B8111200102919

I am located at the very southerly point of Europe in Gibraltar.

In March of this year I t-boned a tired shift worker who pulled out into the main stream of traffic, the result was that I, and the bike, were catapulted some 15 metres over his car. I'm just about recovered from my injuries but the bike has a lot of front end damage. The forks seem to be straight but the fork yokes (triple tree) are completely broken. I'm desperately trying to find some replacement yokes but many I've seen for sale are the wrong diameter. The top yoke with a digital caliper measures 54.93mm. and the bottom yoke measures 58.59mm. 

Can anyone advise on the correct part number for these two items, and the best place to source them? Most that I've located are a much smaller in diameter and not suitable. 

There are other issues with my bike but on different forums on the board that I'll post into,

Very many thanks for any help or advice,

James.

Don't know much about the sm but those forks look like the showa twin chambers on my CRF.

Thanks Broadie, mine are Showa forks that seem to be wrapped in carbon Fibre!! Maybe they are from a different bike????

I'll take some photos of the forks tomorrow and post them up.

Sorry looks like my mistake I'm used to my e with conventional forks on a drz.
Loads of decent chaps in the drz area. Click dirt bike , make and model , Suzuki , drz. I'm probably telling you how to suck eggs, I'll get my coat.

No need for apologies, I'm new here so I'll look up info on the DRZ area. :)

2006 DR-Z400SM lower triple clamp# 51410-29F70, upper triple clamp # 51311-29F70. When I had my 2009 DR-Z400E it had a tapered fork, smaller at the top clamp

Look up you closest Zeta agent as they do a full triple clamp set for a SM. Part number ZE14-3403. Only in black though.

That's the 2nd set of those I have seen photos of, that have ripped the triple clamps of the headstock and the forks appear ok.

Glad to hear you survived.

Thank you all for those invaluable replies, it's much appreciated.

I've just removed the forks and broken top yoke. the bottom yoke looks OK but as seen in the photo, the stem is very bent. Is the stem a tight interference fit into the bottom yoke or is it threaded?

The Showa forks are dead straight so are OK. The wheel is badly damaged but there is a specialist wheel repairer in Málaga city which is about an hours drive away, they show examples of really badly damaged wheels that can be repaired. http://www.llantacars.com/reparacion-de-llantas/

I need wiring advice for the speedo but I've seen another thread on the forum about speedo wiring.

Thanks again, James.
