    Honda CRF450X (2006)


    great bike, tons of power, dual sport capable (and mine is) a little on the heavy side, but i'll get used to it and stronger for controlling the beast that it is haha

    Best bike I've ever had. It's a beast.

    KTM 250 SX-F (2011)


    Perfect for the track and tested in the desert, bought on consignment from a rich guy who rode it once and gave it back to 3brosKTM. Treated well but not pampered to the point where it might miss puberty. It has its early 2010s developmental flaws and requires new gearing to really make it shine, but it provides probably the best love/hate relationship I've ever experienced with a motorized machine. A definite case where the ability of the machine is almost entirely dependent on RIDER SKILL, which I have yet to acquire an adequate amount of! Smooth power delivery, short gears (but a diverse 6 speed gearbox) and very, very satisfying lack of unnecessary weight are the defining features of this bike. Stock Brembo brakes prove KTM's desire to provide performance out of the box. Although it does good in the desert and on the trails (with new gearing), I would recommend the 2011 KTM 250 SX-F fuel injected 4T thumper for track rats only.

    Countershaft Sprocket Removal

    I've been working on fixing a seemingly endless list of dumb previous owner issues with my '05 DRZ400s that I may end up outlining in a post later on if I ever get this bike into a usable condition. DPO replaced the chain and sprockets within a couple hundred miles before selling to me. However he installed a 16 Tooth front sprocket, which is quite obviously too big. The chain has rubbed a nice roomy place to live now and has seemingly NOT caused any real damage (fingers crossed that nothing has really been damaged other than a little case rub..). SO I bought a new 15 tooth to replace it, planning to take a risk on replacing just the sprocket and not the chain as well considering that the chain really is only a couple hundred miles old. However I cannot get the sprocket nut off! I've flattened out the lock washer, and I'm assuming DPO massively overtorqued and threadlocked the living jeebus out of the thing (he had a TT sticker on the bike afterall...) The method I'm using now... using a BFBreakerBar, sitting on the bike with it in gear and both brakes clamped down, all the strength I can muster in that position will not break the nut loose. I'm not opposed to heating the nut a bit but I don't want to risk damaging the seal behind the sprocket. I do not own an air compressor nor any kind of impact wrench - is it time to go buy one or do you have any other suggestions? Thanks, SNH

    This is my 2012 KX250f.. Factory connection suspension, Yoshi carbon fiber full exhaust. Too much list. This bike is a real monster.

    KTM 300 XC (2008)


    I'd rate this bike a 5 star no problem if I had ridden more types of bikes, but since I can't compare it to a whole lot of bikes I rated it a 4. Never any issues. Starts right up and runs amazing. Loves to be lugged and has amazing torque for a 2 stroke. Great woods or motocross bike.
  10. Has anyone ever heard of this, I got a bike and it has a very different rear sprocket on it, every other tooth on it is offset from the tooth before it so that on one link the tooth is against the inside of the link and the next tooth is against the outside of the link??

    Sprocket Teeth: 50 Color: Black Sprocket Position: Rear Material: Aluminum Unique flat face design keeps weight to a minimum and means the TwinRing is as narrow as a regular chainwheel Inner Ring is high strength Ultralight 7075 T6 Aluminum. Outer Ring is Electroless Nickel Coated steel Outer is expanded at 200C and then fitted to inner, creating a permanent bond for the life of the sprocket Precision CNC machined to extremely tight tolerances Flat socket head screws add additional strength to the chainwheel during side impacts Self-cleaning mud grooves between every tooth on both sides help prevent dirt build up Available for most popular dirt bikes with a 520 chain in sizes ranging from 48 to 52

    Renthal Rear Sprocket

    16 reviews

    Sprocket Position: Rear Sprocket Teeth: 47 Aluminum alloy rear chainwheels for Offroad, Road Racing, Road/Street and Kart applications Precision CNC manufactured to extremely tight tolerances from a high strength, specially enhanced 7075 T6 aluminium alloy. Renthal chainwheels have unequalled accuracy of fit, tooth profile and concentricity for longevity and maximum power transfer Maximum reduction of unsprung revolving weight at the rear wheel, through a combination of the choice of material and design insures maximum power transfer. Renthal rear wheel chainwheels are 33% of the weight of steel yet incredibly durable Hard anodized finish

    86 xr 200 chain/sprocket ?

    I have an 82 xl 185 motor in a 86 xr 200 frame and I was wondering if anyone has ever saw a 428 rear sprocket for the 86 xr 200 rim?? the xl185 came factory with a 428 chain and the xr 200 came factory with a 520 and I wanna down size to the 428 if I can. not sure if the 428 sprockets will fit the xr 200 hub. Thanks in advance for the help.
  14. i have a 1999 honda cr125 and i need new sprockets. I use the bike for racing and i want quick acceleration, good take offs, and something that works good for hillclimbs too. I have been looking at 13/52 but i wanted to see what everyone else thought?

    Honda CRF250L (2015)


    Unreal. Really happy so far. I had the stage 1 kit fitted before I took delivery of the bike. Gearing is 13/44. Had Renthal Reed bend bars and Kouba lowering link fitted also. One happy chappy!
  16. I like riding tight trails. But right now my 08 450EXC-R has 15 tooth front sprocket and 45 tooth rear sprocket. It is just to high geared for tight trails on the westside of Washigton. Heck, doing 50 mph on the road it lugs a little in 5th gear and you can not even use 6th doing 50 mph. Just wondering what other people with these bikes are using for sprockets for the trails?.

    Amazing street and offroad bike. With some mods this bike is definitely one to keep.
