We weigh the Yuasa battery in the workshop. I had read that the 20 Ah model that is installed in our motorcycle reaches about 6-7 kg, but when we weighed it we saw that it weighed more than 9 kg.
The guy from the workshop told me that it was normal because they are motors that need good power.
However, the weight of the lithium battery was greater than what the manufacturer said.
The brand of this battery is BS, it weighed more than 2.5 kg and on the web they declared 1.5 kg.
Also in Zard website I found this
ORIGINAL SILENCER WEIGHT: 12.5 KG
ZARD SLIP-ON WEIGHT: 5.5KG
It saves 7 Kg, of course without the catalyst box.
For me are good reasons to think that weight loss is possible.
Other parts like the lisence plate arm, turn lights and fender are located in a bad place for inertial movements.
Relocating this elements with lighter parts may reduce weight and vibrations.
