Another towel please....

 

 

Love me my Yamaha but this wicked looking thing would have saved me a ton of work for the track over the FZ.

And if it's less than $14,100 cheaper too.

Fricken Italians,

I hate my life.

That's one sinister looking SOB! EL Diablo himself would be proud to ride it. I just wonder how much better a parallel twin it has than our 07 or will it be better? Ours has been the one to beat for years now.

My Dorsoduro 750 was pretty reliable. I wonder how good this engine will be.

the rsv4 is nearly 20k  and the shiver is 12k, but it's a naked

It has the looks, we know Aprilia can build chassis that are top notch, the question for me is the motor reliability, don’t get me wrong. I’m sure they put a lot of time into building a solid motor. Is this the revival of the RS 125’s,250’s of the mid 90’s 2-stroke era???? ( Suzuki motors) ^^^^ in the 125’s I’m sure of, the 250’s not 100%. I mean seeming as every manufacturer is trying to get in on the middleweight class and the 4 bangers aren’t as popular as they once were ( zxr 6 <$10k) might help to keep them alive in Kawasaki’s case. I’d like to see what the Moto journo’s have to say after they get to ride them, maybe it would be worth $15k??? I couldn’t afford it, new at least.

OH my lord that is beautiful EXCEPT ...single pivot rear suspension... ERK!!! Having raced 2 single pivot rear ended bikes, I can tell you that getting the rear to behave itself  is a pain. Especially with a centrally weighted bike. No matter how good the rear shock is.

Will it be an awesome bike ...probably. Will it have a good motor...almost certainly ( from the people that made possibly the greatest production motorbike motor EVER, with the worst valves. the RXV and SXV). Will it handle YES... with the proviso that you aren't riding where the rear end has to behave itself well.

Yup, I agree.   I think they got lazy trying to package a better rear shock setup.  And that shock is at a large angle.   A poor motion ratio and a digressive spring rate could be problems.

I disagree about the shock angle. The laydown angle gives a rising rate spring with  constant spring/damping ratios. I designed a suspension like this in the early 70's to do exactly that on my first CR125M when everyone was running 4" of stock shock or doing stupid moving shock lower mounts along the swingarm ( with associated swingarm bending and torsion problems.

The big problem with a single pivot design is it has no anti squat and  the shock is coupled to the chain AND brake torque reactions. Very hard to control the rear wheel under hard acc and braking As the motor and the springing interact, especially as soon as there is uneven surface.

Then theirs also this; https://www.bikesales.com.au/editorial/details/norton-reveals-650cc-parallel-twin-superlight-115757/ I saw a better article about this bike but I can't find it due to being almost , computer incompetent. Food for thought, apparently the TT lightweights are its goal, is what I get from the article! Watchout kawasaki, suzuki, patton. All that for a meager $25,692 USD,✋ (not that it'll make it here) or maybe it will?@ 158 kg's= 348 Lb's outta the box it might be a MotoAmerica twins-cup beater, if it fall's under the rules! I not in anyway clued into the rule's for the twins cup. I just like bike porn.

Happy Thanksgiving people.
