    Hey there, just curious if anyone has run a 15 tooth front sprocket on a 2014 WR300 ?

    If you search there's plenty of gearing talk here, including 15t front sprocket. I run 14t and I guess 15t fits, but gonna' be close. Safer to get a smaller rear sprocket for more top speed and you'll get a slightly longer wheelbase too. :cheers:

    Just the 610 and 630s. I used to fit the old 350 and 610 kick start motors as well.

    Been running a 15 tooth front sprocket since 2006 on '06 wr250, '09 wr300 and '14 wr300 with stock 48 rear. With an auto clutch works great, spreads out the gearing to give a true WR, makes first a little tall but works great with the auto clutch. on a true wide ratio like the older 6-speeds I never used 1st gear anyway except maybe river crossings. With the 15T front sprocket on the newer models I use the entire gearbox.

    I think the 'WR' model designation on these bikes is a little misleading, it refers more to it being an enduro model than it's gearing. Curious, are the gear ratios not the same as the last 'CR' models that they made?

    Either way this has been my best setup, and love my wr300. Every time I ride someone else's bike or a new model, I like my bike even more, best motor out there even compared to the newer stuff.

    BTW 15 is as big as you can go, you might even have to trim the chain wear rubber where it wraps around the swing arm pivot.

    As far as the 17T sprocket goes, it's what came with the Swedish European models that we received in Canada in the '80's. Bikes came with a race kit that had a 13T sprocket among other goodies.

    Interesting thing tho, the Swedish Huskies in the 80's used the same spline and circlip only thing is the it wasn't offset to one side like the newer Italian models. The old Swedish setup allowed the sprocket to be turned the other way for a little extra life.

    Thanks Palito thats exactly what i wanted to know, i am going to run a 50T rear and 14T for tight single then throw on a 15T for firetrails here in Oz .Not much of a gap at swingarm so i didn't want to waste time getting a 15T if it didn't fit Cheers.I can always throw the 48T back on for trails too i guess 15T and 48T would be pretty tall, good high speed.

    Well i ran the 15/48 combo in the Myrtleford Alpine Rally ,which consisted of 75 kms open fire trails in the morning and 60 odd kms in the arvo with a shitload of singletrack and the more i rode this 2014 WR300 the more i loved it .What an awesome bike.The 15 tooth front really suited it IMO.The only other mod i have is a FMF Powercore 2 silencer that comes off a 2000-2006 CR/WR 250 Thanks guys for your input

    I didn't know that a 15 tooth would fit, I have an 14 for trail riding and that did already rub on the chain-slide...

    I think that I'm running an uncommon gearing with 13-45 but I like it, first is somewhat tall but at least I can cruise at reasonable speeds in fifth.

    I don't like the idea of using a 15- with a large sprocket, too much diameter that hit with rocks and too much chain length (weight...)

    Regards.
