FZ8 Full Specifications [gizmag.com]

[Fat Boy]

North American bound?  

Yamaha has finally released full specifications for its new middleweight street sportsbikes, the naked FZ8-N and semi-faired Fazer8. A 779cc engine derived from the FZ1 donk is the star of the show, with a complete FZ1 frame and swingarm as well. The new engine makes significantly more torque than the smaller FZ6 for a gruntier, more accessible power curve around town - but builds to a healthy 105-horsepower top end rush when it's time to get a boogie on. It looks like a fun, fast and friendly street sportsbike - and yes, FZ6 fans, it has formally replaced the 600 in the FZ lineup.



As many have suspected, the engine is indeed a scaled-down version of the fuel-injected 1000cc FZ1 engine, dropped to 779cc by reducing the piston bore, increasing compression, swapping out the pistons, crankshaft and top end. The resulting motor puts out a touch under 105 horsepower, with 82 Nm of torque.

Effectively, that top-end horsepower figure doesn't seem to be much up on the 90-odd rear wheel horses offered by the lighter, 600cc FZ6 donk. But the stroked-out FZ8 makes its power much earlier in the rev range, a fact which should make it a much more willing and eager powerplant around town and in the majority of real-world riding conditions.

Yay for more torque in the smaller mill.

non-Yay for it's still being bigger and heavier mill.

Yay for it being based on the FZ1!

non-Yay for not getting the new, albeit rumored-only, modular mill.

And yay Yamaha for building a street-viable bike not glued to a race class.

465 Lbs in running order, including a fill-up 4.5 gallon tank.  

Loses the fully adjustable FZ1 suspension.  

The FZ8 officially replaces the FZ6, thereby explaining the odd choices made on the FZ6R.

All in all, a good choice.

[Mach VIII]

Sounds like the new FZ8/Fazer8 is closing the gap on the FZ1.

As I read the specs, the only real differences are that the FZ8/Fazer8 will weigh only 20 lbs less, gives up around 35 HP, has weaker brakes, and non-adjustable suspension.  

Assuming it/they come to the US, I wonder what the price differential would be.  If the price is pretty close to the FZ1, I can't see why you wouldn't just spring the extra for it.  If there's a fairly significant price difference (which would seem a bit unwarranted in my mind), then I could see buyers going for the new FZ8/Fazer8 as kind of a budget version of the FZ1.

I do wish they'd offer the naked versions of these bikes here in the US.

Maybe the next gen FZ1 will be of a larger displacement?

[chornbe]

Maybe the next gen FZ1 will be of a larger displacement?

Maybe. But it has traditionally always been an up-sell from its smaller brethren with better suspension, etc., along with its bigger, more powerful engine.   The Gen-II FZ1 was always a nice, soup-to-nuts upsell from the FZ6. I don't see that changing. Even if they don't up the ante on the engine, the brakes and suspension, along with the 200 CCs will always be a viable upsell for the discerning shopper looking to eke out a few more performance points.

Gizmag?

Then it would be the FZ1.1 ?

 Why an 800?  
 Why couldn't it be a good old 750? They already had that engine...800 is just too close to 1000cc.  Unfortunately, here in BC our insurance rates are split into 4 groups, and 750cc is the cutoff for the second rate group, so over 750cc is much more expensive. Those 30 extra cc would cost way too much to bother. I still don't understand why MotoGP arbitrarily dropped displacement to 800cc rather than the "standard" 750cc. The entire 800 class makes no sense to me.

I don't get it either. But I bet their marketing people do, and simply put, 800 is better than 750 to the average person from a marketing perspective; bigger is just better.

 Thats what my wife tells me.....

[D-Mac]

I like it. Not enough of a difference for me to bother upgrading from my FZ6, but if I was buying a new bike I'd take a good look at it. It really looks like the offspring of an FZ6 and and FZ1.

I would think there would need to be a significant price difference between the two to make the FZ8 a viable choice.

I think that the FZ8's market position in Yamaha's lineup will become more clear if (hopefully when) the FZ1 gets upgraded to the crossplane crank from the R1.  Yamaha will be able to use a lot of the tooling from the "old" R1/FZ1 mill to make the FZ8 motor while creating a 25-30% price differential between the FZ8 and FZ1 due to the higher spec suspension and motor on the FZ1.

What I would really like to see is a crossplane FZ1 with a 5 gallon tank and a belt final drive!  

[IrishFazerBoy]

As a concept I like it ... but that seat doesn't look good.    Too sloped!   Ouch  

[nanbil]

I do think that this means that we will see a new FZ1 with a crossplane crank in 2011.  

[ninegear]

not a bad looking bike. for some reason it reminds me of the b-king.

as for its stats its decent.

I don't get it either. But I bet their marketing people do, and simply put, 800 is better than 750 to the average person from a marketing perspective; bigger is just better.

thats probobly what the squids who will buy this bike will think. it seems more squids are going for naked bikes nowdays..well the ones in my area at least.

Splitting the difference between 600 & 1000 seems a logical place to me.

[Campbell]

Yes!!!!! Motorcycle manufacturers seriously need to start bridging the gap between 600 and >999 cc bikes. I love torque on a  street bike, but 650 twins just don't do it for me. Make more 800 inline 4's!!!

750 or 800 twins sound great to me

[Rincewind]

I'd love to see the naked version here in the States.  How many naked road bikes does Yamaha USA offer, not including dual-sports?  Zero!
