Making a Super Moto for the misses.

The guys at Warp 9 are making some rims for me and one of the questions he asked me, "What size sprocket do you want on the rear?" He recommended a 47 tooth sprocket from some other Super Moto customers.

I thought that was a little high, going with the 14 tooth front sprocket. We compromised on a 14T - 44T combo. Get a little more grunt but still not be wringing it out on the highway at cruise speeds (60-65 miles an hour).

Any feedback on the that?

I did find a chart showing you the ratio but it really doesn't do anything for me.


I thought I saw somewhere you would want something closer to 3 for the street.

The first step will be getting the bike down to a comfortable seat height for her (32 inch inseam / 120 pounds). When I sit on the bike I can get it low enough for her, of course I have an extra 100 pounds on me! I'm debating on the lowering link or doing that shock mount drill method.

Going to the 17" wheels and raising the forks up might just do it. Will have to wait and see. Picking the bike up tomorrow from the dealer.

You can get the Tusk handlebar risers from Rocky Mountain ATV and M/C in the 15mm and 30mm size for $17.99 and $19.99, for 7/8 and 1 1/8 bars. I have them and they are very nicely done, I used the 30mm ones on several bikes that I have, they fit the CRF250L perfect.

I appreciate the feedback guys. I'm going to add a little rise, but I don't want to go too crazy.

EJK Tuner Review

Holy Crap! I loved my CRF before I added the fuel tuner. The 13T front sprocket was great and all was going swell...then I added the EJK fuel tuner, removed the snorkel and backfire screen....YEEEEEHAW! Way more power everywhere. I have only done a road test so far, but it really does feel like a different bike (and I still have the stock exhaust). Highly recommended. The bike sounds deeper and more powerful as well. Can't wait to assault Mt. Pirongia on Sunday, the stock rear tire will be toast by the end.

I know this is going to be a stupid question, but can someone explain what the 13T front sprocket does without going into ratios and whatnot? Really what I want to know is, does it allow the CRF to pull the front wheel off the ground in 1st gear without popping the clutch?

If 15T is ok and 14T is better, then 13T must be wonderful.

What are you base numbers for the EJK? Mine is on the way from Dobeck performance. I dont plan on adding an exuast. From your enthusiasm I would say it will be just fine. Have you taken it on the highway? 60+ mph? Mine seems to run out of steam at 65 mph full throttle in 6th with only the 13T sprocket. I am fixing on doing the same mods to the airbox when it gets here.

I was able to lift the front wheel with just the 13t front sprocket. I have also added a 43t sprocket to the rear and it pulls hard. For my riding, the 13/43 is perfect so far and I was able to use the stock chain. If you are looking at sprockets, I highly recommend sprocket center. Chad is a great guy and shipping was super fast.


good luck

I took the bike on the highway for the first time this morning. I only went 1 exit which was aprox. 3-4 miles, (with only 350 miles on the odometer). I could not maintain 65 mph with the stock 14/40 gearing. I am about 300 lbs with all my gear and am wide enough that I need extensions on the stock mirrors. I do not plan on regularly riding on highways but thought if I went with a 13 tooth counter sprocket I would be OK when I have to. I am aprehensive that with your experience that this is not going to solve this minor problem. Iwas originally thinking about a 14/47 setup and being able to put the 13 on when doing tight offroad trails. I guess I will try the 13 tooth C/S sprocket and hope it works. Bill C

My experience was that the bike "loosens up" after a while, and revs better, ect. Maybe wait to decide on mods before you get past the 600 mile service, and start abusing it a bit. Mine has around 1,150 miles on it, and it has a lot more pep now. That said, the 13t is going on tomorrow. I will ride it for a while before deciding if either a 42, or 43 is going on the rear. From what I've read, both will work with the stock chain, 13t, as opposed to leaving the 14t on, and going bigger in the rear.

Not sure what the base numbers are, I will have to pull the seat off to check but they are whaever the EJK team set them at. As far as highway top speed goes, I weigh around 190lbs plus gear and the bike gets up to 120kph very easily now. Beforehand, (with the 13t sprocket) my top speed was around 115kph and it struggled a bit to get there. The power improvement is very linear now, certainly the biggest improvement is in the low/mid range. I change into 2nd far faster now and you can really feel huge power at the change into second. I am a couple of hours away from going out to slay some gravel roads and I'm picking a decrease in fuel efficiency but there is always a trade off. As long as I can go 150kms without having to fuel up I will be happy, as most of the great rides around my neck of the woods have a petrol station at that range. I may still change to a 42T lightweight rear sprocket, but I need to put another 1000kms of varied off road riding before I make that decision. Attention all CRF250L riders: ORDER A FUEL TUNER ASAP!!

Little help please
I use one frequently. Not only for the TAT but if I'm routing out a ride on some back roads, I'll put the roads, turns and mileage on roll chart paper. Makes some think I know the area quite well. LOL

Been reading this forum some months and just got my CRF250L today. I was surprised about the fun one can have leaving the tarmac. This bike steers so quick..compared to my former >liter bikes.

The Dobeck EFI has been ordered along w/Arrow exhaust and 13T is coming next week. Double Take fold-away mirrors where pricey but nice. Still awaiting real result charts before fiddling with the airbox, it seems about sound instead of performance.

Thanks for sharing all these info on this nice bike

(Got the Zeta Impact X1 hand-guards but will return them, they do not fit the stock bar).
