Yamaha Looking To Get Back On Top With 2007 R1

By Alex Edge

According to a report in a recent issue of British weekly MCN, Yamaha plans to continue the trend of using MotoGP-derived technology in their production sportbikes. The R6 was the beneficiary this year (mainly with its drive-by-wire throttle system, developed on the YZR-M1), but rumor has it next year's R1 will receive an even greater infusion of new design ideas that the company has tested in the world's premiere racing series.

The new R1 will almost certainly feature a developement of the same drive-by-wire throttle system used on the R6; in addition, it is rumored that Yamaha will be making some changes to boost midrange power without compromising peak power production. According to MCN, the company recently filed a set of patent applications which show technology that may show up in the 2007 R1: a set of variable-length velocity stacks (like those on the limited-production MV Agusta F4 Tamburini), as well as a variable valve timing and lift system.

Using either or both of these systems could help the Yamaha engineers develop a motor with much greater midrange power than the current model. Different length velocity stacks provide optimum power at different RPM; therefore, variable length stacks allow a smoother, broader spread of power. For more information on the advantages of variable valve timing and lift, see my article from February titled 'The Sportbike Engine of the Future: Camshaft Design'.

Another rumor is that Yamaha plans to abandon the current R1's 5-valve cylinder head for a more common 4-valve setup. This is another result of MotoGP testing and racing - apparently, Yamaha tested 4- and 5-valve YZR-M1s back-to-back last year, and found the 4-valve making smoother power and more midrange.

I'd rather BNG's than a minor update. Means they got it right the first time, and didn't hold back on shit so that they could release it the next year and sell the same bike twice.

HAIL TO THE KING!!

I think regardless of what it looks like its going to be a FAST bike. Definatly going to be interesting to see what suzuki and yamaha cook up for next year. I'll give you guys a first ride report on the Gixxer as we (my dad which by default means me) is #1 on the waiting list for one from honda suzuki of salt lake.
I hope its super skinny like the suzuki 600/750 those things are like dirtbikes!

if left stock r1lover they are close on the track. on the street the r1 is an utter dog until it's regeared or given an exhaust. it acts just like a 600cc bike when left stock. i rode stone's k5 when he had one...pretty good bottom end and it's great compared to the 04 r1. i hope they bring back the bottom end/mid range....suzuki was smart in keeping that.

You are on crack also.......... lmao


Remember I had one just not long ago...... It was not a dog by any means..... it was the most powerful bike I have ever ridden...... and two weeks ago I rode my friends 05 gsxr and imo they are pretty dame close.... yes the gsxr has a little more mid range...... but imo the R1 pulled harder on top.

They are close enough to be the same imo.

Calling the R1 a dog on the street............damn..... lol

Yes if you do gear it down one it's better in the low end, but when I'm riding I'm an R1, I'm not cruising around town on it..................

They key here is knowing how to ride the bike as it was designed. You DO NOT ride an R1 crusiing in the 2000-5000 rpm range..... it was not meant for that at all.... If that's what you want then buy a V-Rod............ lmao

that's my point. if you're out hauling it's fun...but just your normal rides...it was like a 600cc until you wrung it's neck. good for the track or when hauling, but not something i want for a street bike. i want power when i twist the wrist i don't want to have to drop gears or wait for it to wind up. i'd get a 600cc if i wanted that. i want POWER/torque on a street bike

Then here is your answer bro...... :1poke

I have been riding street bikes for almost 20 years and I have never ridden a bike with so much low end.... lol I'm not kidding.... It kick ass on the 0-60 speeds....

lol, no they don't sound anything like a Harley.....

They have a classic Gear driven sound from the engine at low rpms... it'a pretty cool sound...

Mine is a little loud but I will get some clips today... and post them up.
