Yamaha WR450F Amageza build

[alanB]

UPDATE : I have measured my spacers(vernier calliper) and the thickness of the sidewalls(eyeballed it in light and no dents or warps), they are all 100% the same thickness.  SO, Stainless and Nyloc damage was my problem. 

OK 

I wouldn't think you need to torque that thing until your eyeballs bulged so I wouldnt get too carried away with HT bolts etc.  Just get some new nyloc nuts and some normal steel bolts and some nice big/thick washers and it should be fine.

Cyril's bike looks really good - I really like the idea of the exhaust moving to the back and the FI feeding from the top/front - just makes so much sense!

Stainless bolts are just not good enough and HT bolts are the next level up at my local bolt store... they are a bit heavier, but it does not make a difference.  Stainless just strip so easily, so HT bolts it is.

Totally!

And zero fairing.... 2 simple panels from the tower to the tanks, with quick releases.

I am happy with my bike.  I have 2 major structural fixes, one on the exhaust and one patent pending navigation tower fix   ... ok, no, I promised it to be open source, so, I will release cad pics of the plastics soon.

Brilliant read! Thanks

I wish I had the time

Just one other thing I thought of last night.

You may want to consider making the spacers out of aluminium.  I imagine the current nylon one's will compress/flex quite a lot under pressure/stress (no matter how tight you tighten the bolts) which may be part of the problem.  A metal spacer will compress/flex less and thus hold everything that much more rigidly.

Just a thought.

Ja I've been saying for a long time that I did'nt quite see the point of the huge tower and fairing - so like the less is more approach on that bike.

I so want him to finish top 10 with this bike, because that would just prove you can build a low cost bike and win.

His tanks probably cost 1000ZAR in material   His exhaust is routed brilliantly ... and all the exhaust sections parts are sleeved, with springs! Super easy to fix at the bivouac.  If Yamalube pulls this off, it will reset history.

I am sure the suspension is worth 100K ZAR on Cyril's bike, but the rest of the parts are all within a frugal budget's reach.

An interesting thing that I was told by Coma and Despres mechanics at last years challenge is that the  only stock item on the KTM is the clutch casing. There is nothing the same compared to stock 450`s.

I think Cyrils bike has some adjustments made to it in order to compete.

Well done. The wiring was my biggest issue. Ended up making them robust not pretty.

Agree 100%. For example I know on the KTM Cyril had his footpegs turned 5-8 degrees forward, and am sure would have done the same on his Yammie

awesome build boet

[REVS]

Great build pics, well done boet!!!

Inspirational stuff, well done!

Thanks guys.

My build from last year

Oops, ignore the "rakkie" on the back, that is still pretty cool :-D

[Woestynhond]

Dartvader, the safari rear mounted tank, what is the width where it fits over the rear mudguard/ back portion of the seat?

Am really interested in fitting one to my DR , Willing to make modifications  curious to see if it will fit over the sub frame.  Have mailed Safari but no reply.....
Am also in the process of building a rally fairing sort of like this one to go along with the 20l Acerbis tank.

Damn nice build!

Draw me a picture or show me on a photo in my build what you mean.  Mark it with photoshop or something similar.

DV, like im the picture. 

[darthvader]

DV, like im the picture. 

Cool, I will take some measurements tonight.

[darthvader]

DV, like im the picture. 

145 - 155mm

I think the tank is over 7000ZAR, so it is quite an expensive chance to take.  I am almost 100% sure that the tank won't fit over a DR's frame.  As it is, it fits quite tight over the WR's frame

[N[]vA]

oi DV when we doing an Altantis day?

[darthvader]

I have tested a few things out after the race and the first was sprocket configuration.  Now my bike topped empty, at 155km/h.  The downside is that you get totally f-up on 160km/h+ sections, but the technical sections this is king!  I bought a stock 14tooth sprocket and it is a total fu(c)kup, I am going back to 13 on the front.  The bike just feels a tad lazy with the 14...

@audience : What do you run on your 450 on the back and front?

[Pleco]

For what its worth,  I ran one tooth smaller in the front and one size bigger in the back on the klr. It completely transformed the bike. It topped at 100kph at 5000rpm which was perfect for last years rules of 100kph max on the gravel roads.
