As you know, the solution adopted inside the Free Spirits laboratory aren’t end to itself, neither a merely self-referential act of researched beauty.
Don’t ask to Marcello to develop something beauty if it’s not useful. You’d be in dangerous.
Hedonism doesn’t find a home at the feet of Summano Vulcan. We’re not made for it, because we’re in favour of intelligent solution able to enhance riding experience, able to make a bike easier to ride.
Days before we improved the breathing of our Scrambler engine through SF light water proof filters and a new extra TFI unit.
Now, we think it deserves a better final transmission. Chain at the end doesn’t create any serious matter, it may break sometimes of course, but if it’s well kept (clean and greased, for example), no matter about it.
By the way, we’re never totally satisfied and we always struggle to give better (if not the best) solution to our riders.
So, Free Spirits’ team made big attention to the right alignment between transmission pulley and the wheel. Now there is a new belt transmission while at the front there is a 5 mm offset pulley.
Why we wanted to replace chain with belt?
Because belt transmission reduces the loss of power between transmission box and rear wheel and eliminates maintenance (not cleaning, not greasing, necessary on chain transmission).
The 130 teeth belt requires a dynamic belt tensioner (by Free Spirits, CNC machined), designed to keep a constant but light tension on the belt throughout swing-arm movement, the reduced stress and shock loads not only benefit and prevent premature lengthen of the belt but also, and above all, reduces stress from wheel and gearbox output bearings.
What do you think? Isn’t it better and more satisfying to ride your Scrambler now?
