It looks like you're discussing the weight of your electric motorcycles after upgrades! Here's a rough translation:

"My Zebra with full VTB tuning (35kW), all protections, tubeless wheels (18-21), without headlights, lights, and half of the stock wiring, weighs 102 kg. And Sanina with SIRRIS suspension already weighs over 105 kg. For comparison, the new Sur-Ron Ultra Bee 2025 off-road version weighs 90.5 kg out of the box.

Here are the weights, comparing stock and VTB tuning:
- VTB motor: 12.5 kg (stock motor: 10.9 kg)
- VTB battery: 23.8 kg (stock: 20.3 kg)
- VTB controller: 3.25 kg (stock: 3.05 kg)

After tuning, it's no longer a lightweight motorcycle. However, the weight isn't too noticeable, and you get used to it quickly. The difference of 15 kg might seem significant, but with growing skills, it becomes less noticeable."

You seem to have a good understanding of the trade-offs between power and weight. What do you think about the performance differences between your bikes?
