The previous r1 engine to the cross plane was the 07-08 16v engine. First motor with self adjusting velocity stacks. What I don't understand is why not use that head design and air box. That engine ripped.Ak Yammy said:Wha?? Sorry no crossplane motor in the current Apex are you thinking of the EXUP being added? Also as a sportbike nut and rider (2009 GSXR1000) I will tell you the latest R1 with a crossplane motor would not be good in a sled. I have ridden one. With the Uneven firing order they a quite vibey (almost like a v-twin) on accelleration. They do smooth out under steady throttle though. The point of the crossplane was to make a more tractable engine for powering through corners. The response has been lukewarn to the engine as it lacks the punch and scream of the previous (current for apex) 1000 motor. It does provide good torque down low but is not smooth and revs slower.Murse said:Alright I'm done with this guessing game the current Apex 2011-2013 is using this cross plane technology already in it's 4 cylinder guess they are coming out with a 3 cylinder version but looking at mid range applications i.e. vector. So I don't know just wait and see.
Also props to sasquatch EXUP does not add power but does enhance low end power. I could tell a real difference removing my SET (Suzukis EXUP) valve on my GSXR.
Last but not least I would love a current gen Apex with a bit less weight and better suspension/handling. All I ask and i would gladly pay 14k for it and keep it forever!!![]()

Alright guys, This is it! I found this video and I'm sure it wasn't supposed to be released yet, because of the secret track, billet wheels, custom bumper, and 2-1 finger fuel check system, but here is the first view of the proto-type Yamaha 2013/14 retro edition. Didn't expect the track length, but if it can make it there, then the trail must be a breeze.

I figured since Cat went Retro with their mostly black model, we would follow, but this is sick in so many ways

LOL the new 2-1 finger fuel check system is the best advantage of this prototype! But come on yamaha still crappy hand warmers????

Yeah that motor (from the 07-08 R1) is nicknamed the "screamer". Buddy had a 07, we would trade bikes from time to time. The low end was maybe a bit weaker than my GSXR but when the revs came up yowza!!copo427ss said:The previous r1 engine to the cross plane was the 07-08 16v engine.

Yup they could use the adjustable velocity stacks it would add even better response to the low end and work in conjunction with the EXUP valve.

Have had 5 Yammi 4's since the first '03 RX1. Yammi is starting to remind me of poo when poo kept making the same old XC for years and years and years. At the end the XCSP was as refined as it could get and was not a bad sled. The new Apex is the same. It still has its roots in the '03 RX 1. The other manufacturers have not stood still for the last 10 years. There is no doubt that Yammi makes the best trail cruiser. However I have grown tired of the weight. All sleds need to be maintained. Your Yammi may always get you home but you will still need to fix idler wheels and exhaust donuts and other stuff. As far as motors blowing up and frames flexing yes of course these things happen. It has been well documented. You just don't buy those models. I will be looking to test ride each of the other 3 before I decide. I am looking for something that I can actually have some rider input rather than just have a sled that you sit on and kind of point in the general direction you wish to travel. They are simply too heavy to ever handle worth a darn. You are working with some very basic physical forces dealing with motion and inertia. A sled that weighs 200 plus lbs than a late model Apex will be more apt to respond to rider input. Unless you weigh 400 lbs which I do not. So goodby for now Yammi guys. You have all been great and I have learned much from this site. The other sites all seem a little more childish that this one. However I am going over to the dark side. At least for now. If Yammi really does come with something new and different and LIGHT I will be the first one to take a look.

I am holding out for a boosted Apex from the factory like what they are offering on the Nytro. I almost traded in to get the power steering but a boosted Apex would be too much for me to resist!
I asked the Yamaha guys at Hay Days and they said that they could easily do it from a technical perspective but they have internal resistance from their legal department who has concerns about liability issues with a sled with so much power and top speed.
In the mean time I will keep riding my '07 Apex and wait for Yamaha to come up with something new that I can not resist.

Anyone read page 12 of their new supertrax magazine? Suggesting a single platform sled with shared parts like the rev, pro cross and pro ride. Yamaha with one similar model multiple power and suspension choices. Uh oh more rumors

40 LBS. is easy, just take off the power steering. Now take another 80+ Lbs. off to get down to where it should be, or to get even with a 1200 Doo.
I sold the my F1100 turbo Cat because it was still an overweight handfull when trying to run hard, its 65lbs lighter than the new powersteering Apex. They better target a WHOLE lot lighter for the guys who like to ride a little harder. Weight maters I don't care what anyone says. I'm done with heavy machines, but I still want a performance four-stroke that is fun and comfortable. Yamaha has to get with the program and fast!

Maybe its me but I drove a 399lb ski doo TNT and thought it was horrible. I didn't feel the weight difference as much as the slug of a engine. I backpacked with my sled and had over 100lbs of gear with me on my bosted apex and a full tank fo fuel and compared that to the last day with no gear and almost empty fuel (trying to run it out last run of year) which is about 180lbs and again I didn't notice much difference. This is trail riding not mountain riding though. Maybe I dont ride hard as hard as knapp but I just cant tell any difference in weight???? Mine weighs 678lb ready to ride full of fuel I finally got a scale and weighed it myself.
Nothing gives me a rush like my SC apex. Maybe I just like power more then handling and big enough and strong enough to handle it? Dunno. Nothing on the market excites me like my sled does right now though.

I would like a little too heavy over a little too light!
I like being stable at high speeds, but.........
Mike's right though, we are talking 80 lbs range to get where they need to be!
Hope & wait is all we can do! We've told them for years now, did they listen???

What is the difference in weight between an apex and a Nytro and how much of that difference is related to the weight of the motor.
