I'm guessing 12/48 so less rear sprocket diameter to lessen damage?

 

What is more less weight of sprockets and shorther chain.

 

250 exc.....13-50

 

Was 14/52 but going 14/50 tomorrow

 

For dual sport riding it's perfect

 

13/50 - 300 exc 2017

 

Standard

 

13-50 was standard on mine

 

On mine too, as it is standard on all 300 '17 EXC's

 

Mine was 14/50 with 13 in kit.
Running 14/50 now and like it

 

300 exc 14 48 ...... but it is flat here ..............

 

17 300 running 13:50 but thinking of going 13:52 as we mainly ride gnarly tech stuff.

 

Mine 2017 250 exc is 14/50 as a standard with 13 in the kit

 

Im back to 14/52. Perfect for all round riding

 

How you getting on? Do you ride any harder/slower tech stuff?

I ran 14 52 on my 250 berg, then my 250 te husky and was very happy with this for anything from extreme mx h&h and trail riding. Today had first ride on '17 250 exc and used the same gearing. It was fine everywhere but crap on technical hills. If I was a better rider the momentum would have helped me. But it was like been on a 125 today at wern ddu on the hard hills. All or nothing. Im sure its the gearing selection. Going to go stock gears for next ride 13 50 (im sure mine has come with a 51 but from just looking online it should be a 50. Either way im going stock gearing)

 

Definitely wont be changing from 14/52. Pulls everywhere and today was all tight forestry, roots, ruts and holes and knarly climbs. Bike and gearing was faultless.
2nd gear does for all tight going only hooking 3rd a few times to keep momentum.

But i could ride the whole trail in 3rd and lug over roots and uphills with no fear of stalling etc

 

Bike comes with 13 & 14 front and 50 rear. I found 13t snappy so went for happy medium

 

14/52 for me, KTM got it spot on for the 350 with this gearing.

 

13/52 if you want an usable second gear in real tight stuff. I have 13/51 on my 250 Berg. 52 would be better where I ride as I have to use 1st a lot. 13/50 would be tallest I would go, otherwise your creating a gap between 2nd and 3rd, where it will pull 2nd but bog down in 3rd. 14/50 , is what I would use if I was doing lots of road miles at high mph.

 

I literally couldn't use 2nd today at wern ddu on the slower more tech climbs. Where I could on my old 16 husky. Maybe it needs bedding in and loosening up more. Also maybe it's a little rich.

Winding pv to flush with case (yellow spring) could help?

Flapping now I've got tong Sunday on a week old bike I've ridden once and I'm not happy with the setup

 

When you are looking for alternate gearing lets think about maximum torgue vs. top speed.

For me everything longer that 13:50 creates to much useless speed.

I'm after winter ride with 13:52 and it is probably very good gearing for real technical stuff and has enough top speed.

Thinking about going back to 12:50 but I will see in the summer.

 

13/52 is about as low you will ever need really IMO, but I haven't seen your riding area.

 

14/52 imho

 

You only need 1st in the very worst case. It's nice gearing a bike so 2nd is "the new" 1st and your only up from there. No having to cross neutral during changes.

 

I almost never use first, but sometimes its necessary and with 12/50 its useless. I've tried it too. Of course I can only judge using it on the 300. Tried almost everything, but 13/50 is best for me (or 14/52). For less technical stuff 14/52 is ideal as it doesnt create the nasty gap between 2nd and 3rd (like 14/50 does)...

 

I've used 13/52 for the last couple of years in SEEC and find that just about right on my 250xc. Races are mostly woods and fairly tight. For fast stuff like the Hafren I put on a 14 front or a 50 rear. Tried 14/50 one year but didn't like it but carb wasn't quite right at the time.

 

Was it Gomez' bike pictured with a 12 tooth front late last year? Must have been the roof or the one after getzen.

If you need that ultra low gear for trials type turns in rocks etc then if the pros use low gearing it can't be wrong- just make sure you have the talent to cope

 

Alfredo has 12:48 = 13:52.

 

Same Jarvis on his 2017 Husky, runs a 12 front sprocket.

 

12's must hook over quite quick ?

 

They probably change it every race so why would they worry?

Must be other advantages to I reckon. Perhaps better mud/stone clearance around the front sprocket?

 

On my 2017 250 EXC 2t I found the standard gearing it came with (13:50), too tall for the tight technical riding we do.

I found I was in first gear nearly all the time.

Changed it to 12:50 and it seems better, allowing second gear to be used much more.

It all depends on the type of riding you're doing I guess.
