2007 450SXF in the woods

Recommended Posts

I currently race a 2005 RMZ450 in hare scrambles and enduros. I am looking at buying a 2007 450sxf. How does it handle in the woods? How does the e-start work? Any info would be helpful.

You may want to look into the ' 08 450 XCF - same motor but is a 5 speed. Dirt Rider did a test on it this month and liked it better than the '07 450 SXF.

If I was looking at more offroad riding/racing, I'd definitely go with the '08 450XCF.

I love my 450SXF on the track, but I'd have to change the gearing and revalve the suspension for offroad.

The 450XCF would just take a few adjustments and it's purpose built for offroad.

I'm not sure if the tranny ratio is the same, but I like my 505 SX-F in th woods. I dropped 4 teeth on the rear sprocket (and still can hit 128 km/hr!) and have ordered up a 12 ounce flywheel to make the single track a little smoother. I also added a G2 throttle cam and it made a HUGE difference in the woods. I was constantly/accidently flicking the throttle over trail junk and logs and by the end of the day my shoulders and wrists were toast. After adding the 200 cam it smoothened out the lower throttle settings and made the bike WAY more manageable in the slow stuff but the mid throttle hit is still there for getting yourself out of situations. Highly recommend it...

The handling in the woods is second to none and I find the suspension perfect.

However for the amount of money I have spent I could have bought an XC if they offered it in a 505 for 2007.

have you got the 12 ounce flywheel on...? ifso did it make much diff

No, not yet. I have a pre-order in at Trailtech for their first production. When I spoke with them they had just got an SX in their shop to fabricate a flywheel for it. Now that I think of it it was 2 weeks ago...I'll drop them an e-mail and see if they've got it sorted out. Trailtech was the only one who made anything over an 8 ounce weight. 12 ounces is a pretty heavy flywheel weight so it should make quite a difference

I'll PM you when I hear back from them and give a ride report when I get it installed.

Keep us posted on that.

Same here debating the rekluse and flywheel also would like to add 5th gear on my 505 SXF, sucks I just got this bike and they come out with the 505 xcf. If anyone knows how to put in an extra gear please post.

Just curious what your plan is...

Do you intend on lowering your sprocket ratio and then make up for it with a 5th gear for top speed? I gained 4 teeth on the rear sprocket and the freakin bike still does almost 130 km/hr! I ride mainly woods and I rarely touch those speeds so I'm considering dropping my front sprocket a tooth also to shorten up the tall 1st gear of the 505.

I guess I'm just wondering why you'd want a 5th gear on such a tall geared bike...

BTW, I agree on the 505 XC-F thing.... I wish they weren't so tight lipped on new models. A bonus side is that we can add a pile of armour, flywheel weight, etc.. and still tip the scales at probably 20 pounds lighter than an XC:p The gearing thing still sucks though....

So, just to clarify, you put on a 52 tooth rear and are still getting 80+ mph? How are you measuring the speed? GPS?

I am just looking if it is doable I'll do it if not I'll play with the sprockets as to the type of riding. It would be nice to have one more gear when riding between trails.

I thought the 505 had taller gears throughout the tranny ratio?? I may be wrong... If not, wow, you're a fast rider:applause:

I measured it with my GPS and also had a buddy riding next to me on his CRF250-X and that's what his GPS was registering too. I didn't believe it, so I had wifey ride next to me on a rural road. 128 km/hr to be exact...:prof:

Are you referring to 505 SXF ? Cause if you are then you´re wrong on this one. 505 SXF has 14/48 as OEM gearing.

If you mean XCF then you may as well have it right. I don´t know about those XC/XC-W/EXC -models.
