I have a 400, bought it new in 1998, been bullet proof almost, zero motor or trans issue's , BUT have had a rear axle seal leak water in and ruin the rear axle(a COMMON issue on most all honda's with solid rear axle, due to design, Left side only has ONE seal bearing, right side had 2 and thus weak side goes bad?? BUT in almost 2,000+ hrs, and NONE of them really EASY hrs on it, as I have used and abused it more than not, with the things I have asked it to do, an d its been great, I'd buy another one in a heart beat if honda made them again, heck I might buy two if they priced them the same as well LOL
as for top speed, its NOT fast its geared low, its made for work more than fun
I gather you could MAX it out in the upper 40's , but it would be screaming for mercy and I doubt doing that a LOT would be good for long life!
at 25 mph she is rev ing up a bunch, and goes higher in the rpms from there
if you want a good fast trail ATV, this AIN"T what you want
if it was well cared for,(not used as a boat, and basic PM's done as needed)
it should be a LONG lasting reliable atv
they sit LOW< and are smaller sized atv's than, the 450's and up honda's
and by a bunch!
, so for most guys there small in size, but that also makes them nimble and able to get into small places, lower center of gravity too!
I added a lift to mine in 1999, to get it to sit a little higher, I would think MOST at this point in time have also had this mod done
But there solid atv's, NO known issue's with them, MINUS the weak left side bearing, also found on 450's and 500's
Just a honda SRA thing! on axles with the tubes on them and two rear shocks it seems!
