I've seen 153kph on my CRF300 Rally, but these speedo's are definitely optimistic..... more like 140....
But then this is not what these bikes are designed for...
This is one of the reasons why I use soft luggage when riding gravel.... Straps are more flexible for vibrations.
The brackets/clips on hard luggage often fail due to shaking.
I hope you get it back! 🙏
Fuel range will also depend on what type of roads she'll be riding..... soft sand will increase fuel consumption remarkably... I think a tripmeter is probably the best/ most reliable.
I think the issues with EVs is the battery duration and reliability..... This will improve as the technology advances,
But what do you do with the dead cells?
It'll be a new form of pollution methinks.
