The answer is simple: we are waiting on battery technology to get to the point it needs to get to. Currently, its not even close to replace what we can do on our gassers.
Cost, weight, storage capacity. These are things we can't get around, and likely won't be getting around for a decade. There is an excellent YouTube channel called Engineering Explained that does a great deep dive into Tesla's current battery technology and compares it to gasoline. Its a worthwhile watch for anyone wondering how close we really are in terms of storage. Net takeaway, we're probably 1/4-1/2 where we need to be (skewing more toward the lower end)
When we do have a break through on the battery front, however, the entire industry will shift. To those that go "but I like the noise and smell". Cool. You know what we all like more than that? Performance.
For a myriad of reasons, an electric dirt bike that is of comparable weight, power and range will be great for the sport. From noise issues to ease of use, it'll put you, the rider, in a position to simply have more fun. To add, I sincerely believe it'll make maintaining your bike easier.
It is the future. But its also going to stay in the future for quiet some time...
EDIT: TO be clear, we need to get to the point you as a rider can do multiple motos on one battery with no performance loss. We also need cost to get to the point you could throw a few extra in your van and swap them out through the day. For the off road set, we need to get at least 50 miles out of one before its viable. I could see a "moto" battery and an "off road" battery. One obviously being heavier than the other. Regardless, this will be the only way we can expect this to replace what we have.
