09 yz 450 woods gearing

[Dick Falcon]

is the stock gearing good for the woods,i havent got to ride it excpt down the street.I have a rekluse pro,i want to get a good chain and sprockets.thats why im asking.i've been on ktm's for the past 5 years.

I currently have 13/47 on my bike but I am gonna change to 13/49.

Ride it in the woods and then decide for yourself.

[Dick Falcon]

I normally would but the weather in KY is crap right now.lol

Even with a heavy flywheel I was stalling in the tightest sections a lot. I dropped to a 12t countershaft sprocket but haven't rode much with it yet.

[nwbikerider]

Probably depends on your woods, and how fast you ride them. 13/49 is stock, correct? I dropped to a 13/50, and now a 13/52 and I love it. Rarely stall even with the stock flywheel.

I have a 51 tooth in the rear and a flywheel weight. I ride a lot of really technical, tight trails, so I still have to clutch it a lot to keep it from stalling, but the sprocket and FWW help it lug better. Adding a Rekluse would make it perfect. I would suggest a good O-ring or X-ring chaing. The stocker is junk and will stretch every ride.

I have been racing an '08 450F in a scramble series for a few years. I love the set up I have been using to date. 51T rear, stock front and Rekluse Z start pro clutch. I run the hard / hard setting because I like the down low grunt with little slip for when I moto. However, the trick for me has been the use of the MSD adjustable ignition box. 9 different pre programmed settings, 0 being stock and 9 being the most aggressive. HUGE difference in throttle response between 0 and 9. For woods racing I raced on setting 6 in most slick conditions with great results. Very tacky and I would run 7-9. I also ran and DRD Pipe which helped with the low to mid power so I could pretty much run 3 gear most everywhere. This was key for me, as it helped to keep the suspension unloaded in the tree roots, rocks and higher speed stuff. Worked extremely well for me.

I was just working on installing new chain and sprockets today. Mine is an '06. I went with 53 rear. That way, I just put on a 14t front for MX, basically stock gearing. I was going to do the same, but many guys here on TT said to stay away from the 12t front, the small diameter strains the chain and will wear out the swingarm slider faster. 53/13 for woods, 53/14 for MX, haven't ridden it yet. I also got the GYT-R solid chain guide, similair to a TM Desginworks, and DID X-ring chain. I Highly recomend the Dirt Tricks Ironman sprocket, it's lasts forever! Good luck!

I had 13/52 and it was pretty good in the tight woods, I went with 13/51 since I have installed the rekluse pro. 2 links longer on the chain also. 08 450 stock exhaust.

Gytr offroad flywheel next addition might drop to 13/50 if the flyweight give more bottom end.

[bill97gtp]

right now have a 14-front 51-rear.not bad I just ordered 13-front and 50-rear,figured I'll try 51 with 13 then try the 50 to see differences.trying to stretch out second maybe third on trails.now mostly second and first at times.

[bill97gtp]

oh by the way my bike is not a 450 but a 426 if that makes a lot of dif?

It does because the internal gear ratios have changed. Even though the 06+ 450 has a lower final gear ratio (13/49) it works out to be exactly the same as the 14/49 that was stock on the 426.

When you installed the 52 I assume you had to install a longer chain correct? What I really want to know is how much wear did the chain guide get when you went to the larger sprocket?
