There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Should the 2015 Spyder have a bigger engine?

Can non-SL members vote? Thought you had to be registered before you're allowed to express an opinion.
I just love this forum for its unknown standard deviations. :roflblack:

For me the bigger engine desire has nothing to do with more speed. I want smoother, quieter, and perhaps more range and mpg.
Regarding reliability: You would think they would have the bugs worked out by the sixth model year--since its basically the same engine.

Good point; If that is what the larger, more powerful engine delivers. :thumbup:
They're already working on the aerodynamics portion of the equation; the new fenders are the first shot fired in that battle...
If they throw the Bike into an wind tunnel and play with the front-end, I've no doubt that they can make it far more slippery...

A bigger engine would eat gas faster. More/larger cylinders to provide gas to, as well as more weight to pull. Now, lowering the rpms on the other hand.... That would save gas.

Actually there ARE several excuses for that happening...
The better aero package that cages throw into the wind as they move, is by far the most important one! :shocked:

If you want more range, they need a bigger fuel tank...the bigger engine is unlikely to provide what you want. A Goldwing engine in a Spyder would likely get the same kind of mileage. The largest portion of your horsepower goes to overcoming wind resistance at highway speeds. As speed increases, the power requirement increases a a function of the speed squared. I guess if you really wanted to increase the fuel mileage, you'd need a speed governor. 
The other option would be to make the Spyder more aerodynamic. That would require enclosing the suspension, eliminating the styled appearance in favor of a teardrop shaped lump, and closing the rider in more. If I wanted that, I'd buy a Prius. Cutting down the frontal cross section is not an option if you want to keep the third wheel. It is what it is folks. Wanting a bigger engine for torque, speed, smoothness, or reliability are valid desires...but wanting one for better mpg or range is just a dream. The laws of physics cannot be changed.

Since power won't accomplish it, maybe an extra gear will (for us 70+mph drivers).

Unlikely. It takes a certain amount of horsepower to go a certain speed with a certain vehicle. Unless the extra gear dropped you back to a much more favorable spot on a sharp torque curve, you would see only minor changes due to differing engine efficiencies at different rpms. The Spyder has quite a wide, flat torque curve above 5,000 rpm, and horsepower drops off rapidly below that. It might not even be able to pull a higher gear at 70-80 mph. Adding an overdrive would be unlikely to accomplish much, IMO.

Sure there are... And i'll beat Katyln to this one... Especially with cars like the Chevy Volt

Your post sounds like nothing can be done to get more range besides a bigger tank which isn't likely either. Oh well, sorry RT owners....180 miles it is. Glad I got the RS for just sport riding....LOL

Scotty is probably right on the higher gear, though a slightly higher gear might bring some increased MPG at freeway speeds. The trouble is, the cost of adding the gear would likely offset the modest increase in mileage.
But that is not to say that nothing can be done but a bigger tank (which I agree is not likely). Aerodynamics can make a difference and it looks like BRP is addressing this. A smaller windshield will give you better mileage (though few are willing to sacrifice to that degree).
At this point it's 'Love the one you're with'. And really, that isn't all that hard to do.
As far as the RS for sport riding, I agree! I've 'Sport Ridden' from East Tennessee to California twice, Florida 3 times and twice to Canada. Twice I've 'Sport Ridden' over 1,000 miles in a day (stock seat too by the way). Not to mention the short 300~400 mile rides from time to time. Ask Lamont... We have an agreement, I keep up with him long distance, and he keeps up with me in the twisties!

Are there any electronic tricks hidden under the V-8's bonnet?
Chrysler's 300 got better mileage with the 5.7 HEMI than it did with the V-6 models; but it was shutting off cylinders to make that stunt happen.

You make it sound like you are blaming your car for having better mpg! But it's a point well made even so. One reason my car gives good milage is because it's a diesel, but I guess a conversion would be a step too far for Spyder lovers. :roflblack:
