Need Taller Gearing and More power For WR450

Recommended Posts

I love the 2003 wr450, but mostly ride dirt roads and minimum maintnance roads and plan on getting it street legal (if I can) but I've noticed that the bike doesn't quite go fast enough for the type of terrain I ride. Do any of you know what size sprokets would give me the extra top end that I need (looking for 10-15mph) without being too hard on any of the other parts (making them wear out faster)? And are there any reasonable cheap mods I could have a dealer do to get some extra ooomppph out of my WR?

I haven't switched out the throttle stop for the YZ one yet and I tried the grey wire mod, but then my bike wouldn't even start! :cry: Pretty sure I had the right wire.

Again any info would be well appreciated. Thanks

A sincere WR Fan :cry:

Change over your throttle stop for a starters, with the wr stop your only getting 3/4 throttle. What speeds do you want to ride at? I only run 14/50 and have had it up to 170kmh, if your looking to ride at that speed for to long save smashing up a perfectly good bike and just shoot yourself. :cry:

I can go about 74mph tops right now and would like to go about 100 tops. that way I can cruise along at 75-80 without being topped out! :cry: Too much speed is never a bad thing :cry:

If you really want this kind of speed I would suggest you consider a ralley bike. I just bought a KTM 950 Adventure that will cruise at 100 MPH all day :cry:

My stock 04 wr450 with the free mods does the mid to high 80's with all 290 lbs of me on it. I gps'ed it at 82mph, but didnt have it rapped out, so I am guessing I had at least 5mph left in it. Try getting all the "free mods" done, then see if she is fast enough. :cry:
