I think Manufacturers have peaked when it comes to losing weight and tech. you can realistically take the next step and bung in loads of Carbon and Titanium really. but it just would be unaffordable to 80% of new buyers. Ive spent a grand on my new 4RT and it hasn't made it any lighter or a better ride, just a more of a bling ride.
I will look at the 16 model which I have been told are Frame changes and Lighter engine from a dealership.
Have a look at a 08 to 15 beta. is it really so different and much lighter that its earlier counterparts?
All you seem to get is a roundabout of upgrades. this year you have tech fork. next year you have showa. after that it will be tech again..etc etc
