I picked up an 01 Wr426 last year and although I didn't get to ride it to much (knee surgery). I'm just about cleared to ride it now. My questions are that it needs a set of tires and chain and sprockets. What do you guys recommend? I live in Mass and ride mostly fire road type trails with some sand and rock mixed in along with the occassional mud section. Also what would you guys recommend for a chain and sprocket set? I use Sprocket Specialists on my R1 and R6 but I haven't owned a dirt bike in years so any recommendations are appreciated.

Thanks

What size tires? What tooth sprockets? Or do most people just stay stock?

With tires it's always a personal preference. Out west here in CO I like the Maxxis IT's, their cheap and they last in the types of riding I do. Some of my buddy's swear by Dunlops which I have also run and liked just fine. It's really about the compound and tread pattern that will work on the majority of the terrain you want to ride. There is not a perfect tire made for everything in my opinion. As for sprockets, I geared my 01 up just a few teeth for more top end. My friends have been buying KTM's with 6 speed trannie's and I had to just to keep up in the fast sections. Depends on how fast you want to go on the fire roads. My choice on the chains is the Regina x-ring gold. Spendy but hard to wear out. Also, I like steel sprockets. JT, PBI or any major brand will probably do until you find exactly what works for you.

If you don't run through much technical sections, a 15-48 or 15-50 setup will give you better speed on fire roads while remaining easy to deal with in trails.

Following a lot of discussions we had about gearing on this forum, I seem to load the gears more than others. Most guys on this forum run 14 t up front.

It also depends on who you ride with. If you try to follow a XR650r on fire roads, you'll be happy to have a 15 t up front instead of a 14!

I ride a 16/48 ratio off road but my next set up will probably be something more like 15/46-48...

As for the tires, many guys here run the maxxis HT and IT because they are quite inexpensive for what you get. I think the Dunloop 739 is not bad at the rear. I think the front one is a disaster. I currently run the kenda trackmaster front and rear and although they are cheap and they don't show much signs of wear till now, the rear already starts to behave weird in some situation.

My next try will probably be a set of Michelin H12. Expensive but I just have to try em...

You probably can't go wrong with pirelli tires but they are also quite expensive...

Rockymountainmc.com has the MT16 4.50 for $56

I ran the Maxxis IT and found the rear to be fine in a 120 size, but the front was not nearly as good as the Michelin M12 or Pirelli MT44 front. The m12 is the choice in dry and loam and light mud. The 44 is the choice in loam and any mud including the really sloppy stuff.

How did you fit the 16t? I found the 15 to be a very tight fit.

The 14/50 is supposedLy good for 105 wound out. But the 15t does drop the rpms nicely at cruising speed. :banghead:

13/52 Ironman Sprockets, 150/80-18 TeraFlex rear tire, Dunlop 756 front. The best combination I have tried, and the sprockets haven't worn after a year of riding. Oh yeah, don't forget to buy a D.I.D. O-ring chain.

I highly doubt that a 426 could do 105.

Probably more like 90 but it could be possible with someone small.

I am big and I get about 95mph (150km/h) out of my 450 with 14/50 gearing.

Wondered about the 105 myself hence "supposedly" :banghead: Although with a well broken in motor and a tall rear tire who knows. :applause: 90 would still be plenty scary for me... Shoot, 70 mph off road is frighteningly fast in my opinion.

Ha! I am going to go to either 14/48 or 15/50 or even 15/48 for more speed!
You gotta love blasting those big wide dirt roads with ya mates!
I don't like riding with the motor sitting on full revs for long periods of time.

[COLOR=Green]Rear = Maxxis IT 110x100x18
Front = Maxxis IT 80x100x21
I will go with a softer compound up front on the next tire.
(80/100x21 Maxxis Maxx Cross Soft/Intermediate Terrain)
I'm sure your terrain is extreamly different than mine in AZ.[/COLOR]

[COLOR=DarkOrchid]I run 14/50 gearing.
Played with it a little and I think 70 mph on dirt is fast enough for me.
Nice top end while still keeping some of the good lugging ability in the tight stuff.[/COLOR]

[COLOR=Blue]As far as chains go,... I go with the deal at the time I need a new set.
Usually from Rocky Mountain:
Primary Drive Alloy Kit & O-Ring Chain
Fits: 2001, YAMAHA, WR426F $69.99 Part# SK1809
(Currently out of stock)
Not top end stuff but I ride hard rocky trails with water and sand and rocks.
If I bust something it's not that expensive to fix.
And at that price I'm able to have a complete spare set in the truck if needed.[/COLOR]

GOOD LUCK. I love my bike.
Almost sold it but just couldn't do it. I was tempted by all the new shiny bikes.
It has never let me down. Starts on the first or second kick every time and It rips! :banghead:

My bike now with the YZ timing and a new piston revs really high in first and it spins the back tire on the road with a maxxis IT tire.

So your saying that if I go from a 14 up to a 15 it will tame it down??

I do 50/50 road and dirt milage. (I ride from my house to the dirt) and would like to tame the rear end a little, going up steap hills the back end spins alot more in scond gear than it did with wr timing, I didn't think it would make that big of a difference switching to YZ timing.

I run Maxxis tires on my tours because they last great and give good performance. any X-ring chain and a steel sprocket. If you want to get sprocket and chain sets that will last forever checkout sidewinder

15t will tame it- did on mine.

I would read up on the sidewinder thoroughly- I may be wrong but I thought that was a brand someone wrote up recently, advising it was not very durable.

My WR420 will roast the tire just by using throttle, no front break, and not even by dropping the clutch. And thats with a TeraFlex on back. It will spin the tire in any gear, and get the front end as high as I want it to in 5th gear. I'd say that you should leave your gearing alone, and be a little smoother with your throttle. High gearing makes it a lot harder when you get out to the trails.

Weight has no effect on top speed, besides the tiny amount of extra drag caused by a tire getting squished a little bit more. 90 may be right, but I'm not concerned with the top speed on my bikes, as long as its over 60. :banghead: How often do you go over 60 Off-Road? It's not very often for me, so I just go with low gearing to make the most of my power.

I always go flat out, but even if you don't, dropping the gear ratio makes
1st, 2nd, 3rd so much more usable. :applause:

And trust me, weight does have an effect on top speed. My girl can do about
140-145km/h on the 250, I can only get about 130km/h. She is half my weight. :lol:
