Great pipe. I have one on my f4i, the sound is awesome.

bump.

I also have the 700 and love it. Bought it last year while trying to decide between it and the 1000. Decided to go with the cheaper model. Very light and comfortable. Wind noise is less than other helmets I have worn.

Casey looks like he did Laguna Seca with his lid still in the trailer.

Haha, thats exactly what I was thinking.

Congrats, nice pickup. Should look pretty sweet in all white. Now if it would just get warmer...

Another computer geek.... I work as a Network Systems Engineer for the State, which means I do nothing all day but spend taxpayer money.

That sucks, looks like WSBK is the way to go with Aprilia and BMW joining.

I agree with Natedogg and Kawi kid. The Honda F1 team spent over $500million that resulted in 14 constructor points.

Suzuki does rule the AMA series

In MotoGP and WSBK, they are always in the Top 3. Also most of their R&D is done in both those series.

Plus they just developed the pneumatic valve engine and should be even more competitive this year.

Sucks he is getting charged with all 3 accounts. I could see the involuntary manslaughter but the other 2, I don't know. But the cops of course are going to throw the book at him. Exactly why you shouldn't race.

Whats up Tomin? Long time no see.

Yeah, Ive been hiding lately. You still playing ice with those guys? I haven't had my skates on in months, I need to get back to playing.

Sucks you are getting rid of the bike. Not riding it anymore?

Haha, thats a good one.

Dropped the price to $5k for everything.

You trying to sell it to by more hockey gear???

That bike made me realize how profoundly ugly that engine is. Why they insist on building bikes around it continues to baffle me.

Other than the engine, it's not a bad looking bike. Now if only it had the performance to match.

Herd that. You would think with HD emphasizing the engine, they would give it a little more than 90hp. And at 562lbs dry, the thing is going to be a pig.

Yeah, defiantly Isle of Mann TT. I would be scared to bottom out like that.

Think I am going to pick this up after I finish DeadSpace. Heard the multi-player is phenomenal.

Should have read the previous posts before watching that.

Yes we still have red!

Awesome! PM sent.

Right now we only have red and black. Bornsinner MAY have a few sliver ones. We are going to order more very soon.

If you want some for the black and/or red pm me your name (real name) and address. i get them in the mail this week.

I will take 2 in red if you still have them. Will send PM.

Interesting read. I like how they went into the project with goals of more power and better mileage. DuH!!! Who wouldn't want better performance in those two areas? Problem is they tend to be counteractive, more power typically = less mileage. But, obviously they figured it out and made the bike work for them.

BTW those "Click Here" links require registration. But, a good article anyways.

Yeah, those were links to the supplied diagrams that are there. Sorry, just copied and paste from the article.

numbers numbers on the bird. That's a lot crap to sort out to make the bike better. But hey we eventually get the benefits from it.

Agreed. Hopefully the airflow/cooling and engine design eventually gets propagated to the street bikes. Better reliability and more power.

Pretty good presentation/article on the development of Rossi's bike from 2007 - 2008.

Interesting on how their first goal was to make the bike work for the tires and that the chassis was made more stiff under vertical and torsion loads but less stiff under lateral.

2007 Review

Rossi only managed four wins and eight podiums during the 2007 season, leaving the Italian third in the riders' world championship - his worst ranking ever in 500cc/MotoGP and lowest title position since his first season of 125cc grand prix racing in 1996.

Rossi was once again the only M1 rider to win a race and Yamaha was only third in the constructors' championship, behind Honda and Ducati. In terms of results it was Yamaha's worst season since 2003, before Rossi arrived.

A review of the 2007 YZR-M1 highlighted the following weaknesses:

1) Lack of engine performance and reliability, specifically:

*Poor acceleration and maximum speed.

*High water and oil temperature.

2) Hard to manage fuel consumption, caused by:

*Poor Air-Fuel ratio on the track.

3) Difficulties in matching the (all Michelin) tyres to the chassis, resulting in:

*Lack of balance between front and rear grip/braking and turning.

YZR-M1 Development Concept

The YZR-M1's development goals were to:

1) Enhance maximum tyre performance.

2) Maximise engine power.

3) Minimise fuel consumption.

This was to be done by:

1) Chassis: Optimise geometry and rigidity

2) Engine: Less friction and better combustion

3) EMS (Engine Management System): Vehicle dynamics oriented

2008 YZR-M1 Developments and Results

Chassis Developments:

1) CLICK HERE to see a diagram showing how Yamaha optimised the M1's basic bike dimensions.

2) CLICK HERE to see a diagram showing how the frame of the YZR-M1 was changed to improve braking and cornering characteristics. The 2008 frame was stiffer until torsion and vertical loads, but less stiff under lateral loading.

3) CLICK HERE to see a diagram showing how the aerodynamics of the YZR-M1 were changed to improve oil and water cooling. This resulted in more consistent engine performance and improved reliability.

Engine Developments:

1) CLICK HERE to see a diagram showing the main engine changes for the 2008 YZR-M1 compared with the 2007 version.

2) CLICK HERE to see a diagram showing the main improvements in engine performance. The pneumatic-valve system (first introduced during 2007) reduced the weight of the valve-system by 40%, lowered the amount of spring force required and allowed for a higher valve lift.

Engine losses due to friction were reduced by optimising the piston and ring, changing the crankshaft diameter, using a new centre oil feed lubrication system and changes to surface treatments.

The above modifications resulted in a 12% increase in maximum power and 8% increase in maximum torque, compared with the 2007 engine.

3) CLICK HERE to see a diagram showing the increase in maximum speed and reduction in fuel consumption, for each track present on both the 2007 and 2008 world championship. The biggest top speed improvement was 16 km/h at Qatar, while the M1 was over 10km/h faster at four other circuits. The biggest drop in fuel consumption was a 13% improvement at Estoril.

EMS Developments:

Summary of 2008 Season

The 2008 YZR-M1 achieved all its racing objectives, winning the riders', constructors' and teams' MotoGP World Championships.

The YZR-M1 took victory in ten out of the 18 rounds - nine wins for Rossi (Bridgestone tyres) and one win for Jorge Lorenzo (Michelin tyres) - and a Yamaha rider finished on the podium at every race. The 2008 YZR-M1 concluded the season with 10 wins, 24 podiums and 7 pole positions.

In brief, Yamaha improved maximum tyre performance due to:

1. Chassis dimensions being modified to suit the tyre.

2. A new EMS [Engine Management System] strategy to maximize tyre performance using vehicle dynamics.

Yamaha's work to maximise engine power and minimise fuel consumption resulted in:

1. Engine performance being improved by 12%.

2. Fuel consumption being improved by 6%.

Oh it'll go back up slowly but surely. the election is over, the holidays are coming.

I agree. I think the gas stations are just trying to maximize profit for the Holidays. Right now the price per barrel is about 60% less than it was earlier in the summer. Gas Stations largest profit margin is from what people buy in their store (snacks, pop, etc) and with the way the economy is right now, consumers are not making the extra purchases.

By charging .20cents more a gallon they are profiting while gas is still looking cheap to us. Here in Columbus I have seen gas range from $1.77 to $1.97, all in about a 5mile radius.

A buddy of mine that was station at Camp Lejeune said that they were banned there. Same thing, too many people were dieing on them.

on Cleaner's comment.

Wow. That's unlucky for the Seattle police department, they just picked a fight with the Hells Angels.

even if you spent your youth on go-carts, DOESN'T mean you should have a corvette as your first car.

just because you spend your youth on dirt bikes DOESN'T mean your first street bike should be a literbike.

regardless of the consequences, it was a bad call.

It's unfortunate for his family, and I'm sure his father is kicking himself harder than anyone right now.

This was just an unfortunate accident from a kid who was 16 years old. The article stated that the kid;

"grew up on motorized bikes, quads, Sea-doos, ATVs and motorcycles since he was 18 months old. Allen permitted Austin since age 15 ½ to ride his Yamaha FV6." And the father had preached safety first and ridden with him the kid was 16. The father had trusted his son on a bike and was trying to make him happy.

How many times when you were 16 did you disobey your parents? I can count endless times. The father just made the call based on how well his son and ridden with him. He trusted his son that he would make the right decision on the bike. Didn't matter if it was a 600, 750, or 1000, the kid would have done the same thing.

It is just a very unfornate situation, were the kid "disobeyed" his father and ended up getting killed. I feel very bad for the family, especially the father. R.I.P.
