M401/M404 Tire Combo?

Recommended Posts

The previous owner of my 2007 Kx250f had the Bridgestone M401 front tire on and a Michelin Starcross 450 size tire on the back. I did my research and read that the 450 size tire on a 250 causes some drag and a tad bit more load which makes complete sense. I would like to buy a 250 size rear tire (100/90/19). What do you guys think about keeping the M401 in front and slapping on an M404 on the rear? I know it's best to keep the corresponding tire combo...

My reason for asking is because I no longer see the M401 or M402 for sale on motosport or rockymountain, does Bridgestone no longer make these tires and substituted them for the M403 and M404's? Thanks

Yea I figured they were the same, just replaced. I know it's best to keep the same tire choices for front and back so I just wanted some feedback on the mix. I want to get rid of this 450 tire!

Ok... it appears I should have done a little more research than I originally did. I read in two different threads that the M403/404's are the replacements for M401/402's.

So my question of whether or not running my M401 front with M404 rear would be the same as the original M401/402 combo seems to be answered.

Seeing as M401's are no longer made, I'm suprised at how much thread is still on it, he must have gotten it right before the transition I suppose.

The only question I have left now is a matter of everyones opinions.... my rear tire still has decent tread left on it.... should I stick with my rear Michelin 450 size 110/90/19 Starcross Sand 4 tire and Bridgestone M401 front tire? Or is that all together a weird combo? My thoughts were that it was an odd combo the previous owner had on there, but plenty of people on here know alot more than I do so any opinions will be appreciated.

Anyone? I could use a few opinions. I just want to know if it's best to buy a better matching rear tire or just stick with my current combo...

Thanks FMXRider, I'm gonna end up doing that. I would like to get this 450 tire off here and see how I like it with the regular 100/90/19 size tire

just use the tires to the rear wears out,then put a new 403/404 combo on. no need to worry so much. the 404 rear has a 110/80 19 tire of choice for many just picked on up will give ride reviw in future. one of my friends uses it and loves it. ost pros used it last year.

      I recently bought a 2012 kx250f. The guy I bought it from said he never adjusted the valves, but the previous owner bought a new engine in 2014. The bike is burning oil (I haven’t had a chance to do an oil change yet so idk how much) but it burns on startup, and when the bike is revved high quickly. It isn’t hard to start, every time I’ve started it it only takes 1 kick. I’ve heard it could be the valve guides, seats, or the piston rings. Any suggestions on what it most likely is?

      Hi, I have just bought a kx250f, 2013 with a freshly rebuilt 2016 motor in it, this is my first time on these forums, anyways, I have also bought a lowering link to drop it 4 inches on the arse, I was wondering if anyone knows how much I should drop the forks? 
      I havent put the lowering link on yet. 
      Thanks.

      Recently had issues with the original fcr carburator that was installed in my 2009 kx250f, tried jetting multiple time and different gas and the bike would only run with the choke ziptied out. Do I went ahead and purchased the lectron gen 2 4 stroke carburator kit, was kinda expensive and I was kind sceptical but after my first ride all I got to say is wow. The only adjustment I have done it set the idle, the bike runs amazing and feels as if there is more power than before. The kit came with a new throttle tube assembly and a g2 throttle tube with adjustable cams for throttle response. I highly recommend if you have a carburator on your four stroke and don't want to get a new dirtbike that is fuel injection then go the route of throwing out that junk fcr carburator and get a lectron gen 2 carburator for your old 4 stroke

      I own a 2012 Kx250F that I would like to make street legal if possible and I recently saw Rocky mountain I believe sells these battery packs that sit in the airbox for bikes without batteries that looks too good to be true and a headlight and turn signals like a conversion kit basically and I was curious as if anyone has had luck with those or if there junk it would be nice to make my bike street legal for short trips or just have lights for trail riding with friends that already do if possible any tips on converting it?
