R1與R6,YAMAHA宣稱R1的骨架縱向剛性增加百分之多少,橫向剛性增加百分之多少......但,我看了之後......很懷疑,還有04'R1的後懸吊怎麼好像只是03'R1與R6(甚至其他款)後懸吊臂的倒置?如果只是倒置的話,很懷疑YAMAHA組車的原則......04'R1真的很美也很讚,但......許多部分也亂怪一把的,是否只是求前衛而欠實際呢?

Yamaha 2004 Sportbike lineup
2004 YZF-R1
You're looking at what Yamaha says they're learned in 50 years of competition. It begins with anew third-generation, 998cc, liquid-cooled, short-stroke, 20-valve, in-line four-cylinder engine designed to make 180 horsepower power at a stratospheric 12,500 rpm. The shorter cylinder head is re-angled farther forward to 40 degrees, far enough forward to allow the main frame spars to go over the engine instead of around it.
 That straighter load path makes the Deltabox V frame massively strong, even as it makes the bike narrow to better fit the rider. Together with its light, strong and long Controlled Fill die cast truss swingarm, all that power is deployed to the pavement with the help of a fully adjustable piggyback shock absorber. Titanium exhaust with Yamaha's lightweight Exhaust Ultimate Powervalve (EXUP) is routed under the seat for greater mass centralization. 56 degrees of cornering clearance is a good thing too. New, five-spoke wheels at both ends are light to spool up fast. Radial-mount forged calipers and 320mm discs provide outstanding braking performance for bending controllably into tight chicanes at the end of long, sixth-gear straights. |  |

2004 YZF-R6
Something old, something new, something blue? Newly redesigned for 2003 from the ground up, the 2004 YZF-R6 just gets minor revisions midway thru its 2-year design cycle. Still, if you never let the YZF-R6's tachometer needle roam into the second half of its arc, you might never know what's lurking there waiting to be unleashed. And... here's what's new for 2004. An ingenious suction-piston fuel injection system (re-mapped for '04), among other things, endows it with amazingly goodroad manners at low and medium engine speeds. But we had a higher calling in mind for the little beast that won the AMA Supersport Class Championship** right out of the gate as well as Cycle World, Sport Rider and Motorcycle Online 600 comparisons.* A 15,500 rpm redline. Redesigned exhaust canister providing improved exhaust flow for 2004. This one is pure sportbike, designed from the asphalt up to achieve a delicate, sublime blend of handling and horsepower, finesse and feel, hyperactive agility and laser-beam predictability. Absolute leading-edge technology takes tangible form in the R6's light and rigid DeltaBox III frame - an almost seamless pieceof alloy artisanship that allowed the engineers to put strength - and the revvy 4-cylinder - exactly where they belong. From there, all sorts of good things flow. 2003 YZF-R6 Specifications
