Understanding Gearing and Sprockets with Geoff Ballard | MXstore.com.au 

Only 3k subscribers 😳 unbelievable best and most sensible advice out there. All his videos are absolutely spot on. 👍👍

Another good point made, about the rear axle position changing how the bike handes. I went ahead and picked up a sprocket and chain upgrade set (chromoly gears and o-ring chain) with both a 13 and 14 tooth front and 51 tooth rear that allows for the 3.92 ratio setup to have the axle moved back a bit and with the 3.64 ratio it's right in the middle. Works sweet if you plan it out to allow both ratios to have adequate slack adjustment left over.

Love the info from a true pro like Geoff. Just subed

Hey mate great video, just curious where did you get your black bracket you have under your rear mudguard for your tail light cheers ?

Good tips

I ride a WR250F, was considering trading out the stock 13 front for a 12 to slow the bike down a bit in the tighter terrain. Is this a bad idea?

Please help, i have the same bike and have put a 14T front sprocket which is 1 tooth bigger than standard, do you guys make a Case saver that clears the bigger front sprocket?
