CRF 450r Sprockets and Trail riding

Recommended Posts

I have a 53 tooth sprocket on the back now.  I have a 13 tooth on the front.  If I put a 12 tooth on the front what will happen to the speeds in 1st and 2nd gear?  I am trying to gear the bike down for slower trail riding in the hard stuff.  Give me your thoughts or better suggestions.  Thanks

13 51 at the moment but looking at 14 47 at some stage. More FWW is the real key imo.

Slipper clutch and/or heavier flywheel. The 450r already has enough bottom end.

I run 13/52 or 12/52 in the woods, awesome for crawling up nasty hills between trees.

OK.  So I am having trouble replying to these threads on my smart phone.  I think I am in and out of service.  Anyway,  Thanks for all the replies.  Im just an old guy that just cant keep up anymore with the bike I have but dont want to sell it as I love it so much.  I just need to slow it down in the difficult areas on trail riding so I dont have to work the clutch so much.  I was hoping that the 12/53 would do the trick for the tight trails.  I dont care to much about top speed anymore.  I just dont race around to much and instead enjoy the trail riding where we are in 1-4 gears anyway.  Are there any other inexpensive ideas for trail riding that you all can suggest that will help the old and frail ride easier without cahnging bikes.  I cant give up my 450R.  Love it too much.

Setting up the suspension to suit you will only make the bike easier to ride

Like someone said, a flywheel will help you out a lot. Then you can lug it at slower speeds , and in the tight stuff. Adding a flywheel is easy too.

If this is an EFI bike, it's very easy to tone down the power delivery and abruptness with a simple, cheap, remapping of the stock ECU...
