Anyone know anything about this?

[Dogbytes]

Love it, can't find out anything about it.

Purposeful looking beast. The numbers on the tank might indicate it's run at Bonneville (1000cc, Modified frame, Pushrod engine, Gasoline).

The logo SW and the name 'Skrunxwerks', yes spelled like that, appear on the swing arm. Doesn't show up in a Google search.

Whatever it is , I'd love to know who built it.

It's a salt flat bike from oz, there's a long thread about it over on advrider, 'airhead salt racer' or
something like that

Worth a read, his work is top notch, his name over there is adrenal

Perfect. Thanks very much, I'll have a look.

Mis-spelling of the name name to the low-res pic. Via Advrider posts I've just found his website http://skrunkwerks.com/skrunk/skrunkwerks-bmw-r100-salt-racer-2/

His work does look very nice.

He built his own rolling road to test it on. he's a really nice bloke as well (haven't met him but sent him an email a while back).


not sure why he has a gay label sticking out the back of his hat though.

 

[Dogbytes]

And he lives in Melbourne too. My favourite city, lucky b******

That rear peg arrangement looks "Fragile" ......

Nice concept otherwise

I think it's probably to aid an aerodynamic riding position - with just his feet hooked on it won't have to take much of a load.

I imagine pegs are an after thought on a bike built for all out speed on the salt

You could be right but I doubt it - if I were building a 150mph airhead I'd make sure the bits connecting me to it were pretty secure! I just think they don't need to take much stress - not like a PD racer where you'd be standing on the pegs all day, flat out on rough/no roads.

thats maybe 40 ~ 50 cm approx of leverage on something that does not appear to have any lateral bracing

So as you try to Hold On to the bike to resist wind force plus forces of acceleration what do you push or pull on ????

I reckon that a fair proportion of your energy to stay on, will be through your feet !

Thereby pushing those two spindly looking "things" in towards an undulating swingarm at 150 mph plus


Am I wrong here ???

 

[Dogbytes]

I do take your point but things can be stronger than they might appear. Purely from the look of it I'd be more worried about the seat which also looks like it might head towards the wheel. However, given that the guy who built it also rode it, I think he probably took a bit of time to think about it. Makes mine look a bit over built!

you would be doing very well to hit 150 on an airhead on salt flats, supercharger would be needed
for 150 plus on an airhead I reckon, I think he got round 120ish

A single bolt through a machined bit of billet would be plenty strong for that, if you read Adrian's thread
on adv you get an idea for the guys attention to detail for the task of salt racing, not much was left to
chance

O

You're correct, he got around the 120 mark but that was with the engine from his road bike fitted - the proper engine, which he expects to make 40 bhp more, not being finished.

I'm pretty sure naturally aspirated airheads have done mid 160s at Bonneville - albeit faired.

I'm sure you're right, I just looked at his thread there and he dyno tested the bike as raced and it
had 60hp at the wheel. Didn't think it was that low, 160 doesn't seem that high a speed now!

 

[Dogbytes]

160 doesn't seem that high a speed now!

Things have certainly moved on since Airheads ceased production. In speed terms anyway. I've been, half-heartedly, trying to find out what the LSR for an unfair edge, pushrod-engined, 1000cc class bike is. I reckon it's under 175mph (which would certainly take some doing - as would hanging into the damned thing).

I wouldn't mind having a crack at that kind of thing.

Regrettably Bonneville speed week may be a thing of the past. Two years running now it's been cancelled due to poor salt conditions. Maybe somewhere else in the world?

Have a word with Richie. He was involved with the Salt racer at one point. I think he supplied another engine to another Australian who went on to set the speed record in his class.

Yeah, I read that. Shame, so many people must put so much effort into preparing for it. I'm sure it'll be back. There are several other venues but I don't think any have the kudos that Bonneville does.
