Whether it’s rocking out at your favorite bike park, nailing that drop-in at your
local freeride spot, going big deep in the woods, or even a little street or park
action, the Yakuza series has a bike to fit your needs! Progressively designed bikes
to fit your aggressive riding style. The 8” travel Yakuza downhill frame used on the
Kumicho and Sohon Bucho features details found on higher end dh bikes, such as
an 83mm bb shell and 150X12mm hub, combined with our single pivot rps suspension
system to give you confidence at speed and over the nastiest of terrain. The 7”
travel Yakuza freeride frame found on the Ojiki and Aniki models features our cps
suspension system to soak up the big hits but still allowing you to pedal back up
that next climb. Finally, the Yakuza hardtail featured on the Chimpira is among one
of the most versatile hardtails on the market; burly, stiff, and nimble it is perfect
for deep woods jumps and hucks. Of course, all of our Yakuza frames feature 1.5”
headtubes for strength and compatibility as well as replaceable hangers just in
case you come up short on that next landing.
(R.P.S.) REARWARD PIVOT SYSTEM
Our distinctive looking rearward pivot system (r.p.s.) is much more than a new look
for single pivot bicycle designs, its a revolution in performance. This system was
developed in part as a result of Iron Horse’s world cup and world championship
winning downhill program. First debuted on the Yakuza Kumicho downhill platform,
it has now migrated across the line of full suspension offerings from Iron Horse.
The system features an improved pedaling response over other single pivot
systems, along with great bump sensitivity, and low pedal feedback on the big hits.

Strengths: Overall durability, I love it. Feels great all around, even with the weight. Takes off as soon as you hit any kind of slope, no pedaling practically. Heavy duty, no doubt.
Weaknesses: Suspension and Shifting. My bike ghost shifted like crazy so I had a friend help me out and tune it up, ended up changing the set up, no problem now. I'm a crazy light rider, not even 135lbs and I can bottom out the suspension pretty easy, i bumped up to a heavy duty coil in the rear and still could bottom out (broke my seat.) Replaced the front forks with some 888's and it's even better now.
Love the bike. I've had it forever now it seems and it still works great for everything I want to do with it. Only downfall is the rear shock. I'd also recommend a guard for the front sprocket, nothing protects it if you mess up.

Strengths: 2006 Iron horse Yakuza Sohon Bucho..Very strong well designed frame, Single pivot swing arm is well designed with no side play and no adverse tracking issues. I prefer it over multi link designs, Great for drops, have done 52 ft drop with no damage have even done a 48 ft drop on Shale with no damage. I average 20 to 40 ft drops and jumps frequently on this bike with no issues!!!! GREAT FREE RIDE OR DOWN HILL BIKE!!!!
Weaknesses: Stock Manitou Metel Rear shock Bottoms out causing rear tire to hit seat.. Front fork bottomed out too.. All good now, I replaced them!!

Frame is bullet proof... Only way to snap it would be landing on a boulder..
It does not get any better than this, My Yeti 575 has half an inch of dust on it in storage shed that testifies how good the Yakuza is.
I cracked my rear triangle/swing arm for my iron horse yakuza sohon bucho and was wondering if anyone could help me out to find a new or used one. Its the same frame as the airborne taka.
Thank you.Read More »
Hi all, I just recently got an 06 yakuza sohon bucho. Everything I have read about this frame tells me that it has an 83mm BB, but when I got the frame I measured the BB out to 73mm. The frame also does not have welded on ISCG tabs, so my question is do do I need some kind of spacers and ISCG moun ... Read More »
Check it out. Just got her on there today and put her on the scale.
39.91lbs. Scary good compared to the 46 or 47 it was stock. plus there are still some heavy parts on it. The stuff saving the most weght is the air rear shock, and the Ultegra Road der and cassette. Plus the velocity rims ar ... Read More »
I just bought the Sohon Bucho and was wondering if there was anything I should know about the bike. Any Negatives that I should be aware of. Even positives would be nice to hear. Also if you have any pictures of one in action or just a decent picture... Please share!Read More »
I've got the freeride bug real bad, and the Randal Scott '06 prices on these two bikes is simply too hard to pass up. My dilema is this...I ride mostly moderate single track. A cross country racer couldn't handle the wash outs and roots, etc very well, but an all mountain type bike would laugh at th ... Read More »
