Yummy bike porn.

 

I'm still trying to understand what the horizontal tube below the engine in photo 9 is for. I saw it all season and couldn't find out an explanation for it.

"That web joining the front engine bearer at the left to the chassis beam comes straight from MotoGP, where it was developed to improve the compromise between some lateral flexibility (to keep the front tire hooked up on rough pavement) and the need to prevent the steering head from being flexed by braking force."

I'm guessing this is the description for it, but I don't get what it's possibly attached to if so.

 

Is that not a side lift point?

Oh snap.

 

sweet bike

 

Holy...damn...zexy

 

That’s awesome, too bad hardly anyone will see it on track

 

Why’s the article read like a bad translation from a different language?

 

I think it's a fairing mount. It isn't exactly round, nor thick wall, and there is a dzus (or whatever) on the end at an angle. I have had several bikes that have a tube across the bike to hold fairings in place; sometimes they were fastened to the bike, sometimes just across the fairing for support.

If we're guessing and all.

 

That's just Kevin. Brilliant, yet, at times, his writing is a bit of a challenge to read.

 

It was there all year. It looked structural but it only showed on the right side of the bike.

 

It’s a receiver tube for the spear stand.

 

They didn't believe me Chuck...LOL

 

Im not keen on the clearance notch for the exhaust in the swingarm. If even just heavy contact and no fall the exhaust could easily be tweeked enough to interfere considering the conservative clearance and maybe cost you positions or even the race. You would think it would be easier to route the exhaust to accommodate the swingarm rather than alter the swingarm to accommodate the exhaust. Just strikes me as curious.

 

Suzuki killer...

 

Not so much wouldn't it be easier but, wouldn't it be a more crash or impact durable result?
