I lived 3 miles up a dirt road… I wouldn’t take a ninja 250 on it… sheeeee’t thats why my dad sold the vet- it wouldn’t hold up to that.
Most 3 mile long dirt roads AREN”T well maintained unless they are fireroads or something a larger entity is paid to mantain it as such. If it was a properly placed DGA/RCA/asphalt milling/ road- yes it could be very well held up- even for a private road- but I doubt 3 miles of private road was so meticulously placed- its super expensive.
Most privately owned/shared roads (ours wasn’t privately owned- we all beat it to death and many of us tried to help maintain it so yeah “maintain” takes on a whole new meaning) …are not made of the finest materials- just whats there- and they aren’t super well maintained (if you’re’s is- then clearly this need not apply- but for sake of discussion) and NO it would not be an appropriate choice Could it- sure but you’d regret it immediately. Find a way to keep it off the road for the most part- (friends garage/storage etc etc) or get a dual sport- I think you would be wincing every time you took it out. and no one wants that!
