250's gear ratios?

I'm still considering a new 2010 TE250 but wanted some info on gear ratio's.

My ? is what gearing does the te 250 come with stock and what you would recommend as a good starting point to ride the bike as a "dirt bike" and not a street bike. My intentions are to ride trails and desert style riding (not racing) and only to use the bike on the street as a "connector" to other trails.

Also, what gearing does the tXC come with as well? (just curious)

TE250 stock gearing?
TE250 recommended?
TXC 250 gearing?

Thanks.

All are 13/50 which on my TE250 2010 makes 1st gear about the same as 2nd on a 250exc.

I do find 1st gear a bit tall, especially on trial's type going...

13/50 is a good starting point for your 250.

The US model does come with a o ring chain and the 40 tooth rear installed and another o ring chain to match up with the 50 tooth rear sprocket supplied.

The front is a 13 tooth stock and as far as I know the front in a brand new one(shaft change) and not available in any other sizes aftermarket and I have a 12 tooth on order when Husky releases them.

The TE and TXC are the same ratios

Trans ratio 3,076

Final ratios
1st 20,944
2nd 17,104
3rd 14,172
4th 11,995
5th 10,181
6th 7,964

Don't realy understand that but:

250 exc-f:

Primary gears are 68/22(3.09)
!st gear ratio is 33/13(2.54)
2nd gear ratio is 33/17(1.94)
Final dive sprockets are 50/13(3.85)

To me that gives overall ratios of 30.178(1st) and 23.077(2nd).


2010 TE250:

Primary gears are 54/17(3.18)
!st gear ratio is 30/14(2.14)
2nd gear ratio is 28/16(1.94)
Final dive sprockets are 50/13(3.85)

To me that gives overall ratios of 26.180(1st) and 21.38(2nd).

You can ignore the road going rear sprocket.

I think you can see first is way high compared to KTM...

13 front and 52 back sprocket would make things better at 27.23(1st)

12 front and 50 back sprocket would give 28.36(1st)

12/52 would give you 29.45(1st). Where the KTM is 30.178

12/52 would look weird on the bike. I also think that a 12 tooth front would wear the chain and swinging arm out quickly...

Difficult ion the TE250 to get a low "Trials" type gear!!!

I meant to say:

Difficult on the TE250 to get a low "Trials" type 1st gear. Wondered why I have to slip the clutch so much in first.

regards

I have an 08 TXC250...Its transmission gears are as follows: (Same for the TE & SMR models)

1st -- 2.000 (28\14)
2nd -- 1.611 (29\18)
3rd -- 1.333 (24\18)
4th -- 1.086 (25\23)
5th -- 0.920 (23\25)
6th -- 0.814 (22\27)

The 4 ratios in bold are interesting as it appears the bikes are higher geared in 010. And changing the sprocket sets will never change the internal ratios

Can someone post a list of the actual tranny gear ratios for 2010 TE/TXC beside ray-ray's list for 08? Not overall gear ratios, but the actual tranny ratios........

Based on published figures* I found on another site, it appears that the new TE/TXC 250's use the same internal ratios as the 04-09 models.

*accuracy unverified

Here is a link to the spec sheet for the 2010 TE250 from the Australian importer's web site. The internal gear ratios are listed.

http://husky.com.au/2010bikes/te 250/te 250-10ie.pdf

1st 2,142 (30/14)
2nd 1,750 (28/16)
3rd 1,450 (29/20)
4th 1,227 (27/22)
5th 1,041 (25/24)
6th 0,884 (22/27)

So it's different from earlier models but not by much and the span from low to high is almost the same as before.

Hey guys,

Am I the only one that finds Husky gearing kinda weird?? First seems too tall -- as someone mentioned, when you want to poke along a tight or technical trail you have to do a lot of creative clutch work -- but then it seems the 6th gear is too short. These bikes have power to spare and could pull a bigger (read higher top speed without reving the shit out of them) when you do have to drop onto a groomed gravel road or paved highway for a road transfer section.

If anyone from the factory or design team ever reads these posts, that may be something to pick up and take back to the boyz in the design room. I have very few complaints of my 09 TE, but this is one of them.

Just looking at the numbers here, the 010 gear set starts a little higher and ends a little higher from the 08 \ 09 models. How about the spacing between the gears? Any big jumps or obvious jumps too small there? This would be a big problem. I have rode bikes that the gear spacing are too large or too short and it will truely screws a bike up to a high degree.

Also, the terms used here are a little ambiguous..What is poking? What is a technical trail? And what is a tight techinal trail? Getting any tail on this trail as you are poking around Sounds a little like trials bike riding. They poke around...

I'm not a mechinical engineer but I'd think engineering a machine that is going to be used possibily world wide will have limitations, ESP if it could be start downtown NYC and then go to the top of a mountain on a dirt road or hard top.

I'm fine with my 08 TXC250...I can gear it up or down with the sprocket sets to fit the riding I'll be doing each day and I don't expect my dirt bike to climb straight up a mountain side in GPNF and then go down a fire road at 80MPH easily ...

I can't read this PDF file and are these the same gear ratios for the 010 TXC model?

One must not forget the primary ratio on the 2010 TE250 which is 54/17(3.18). As we are really talking about the 2010 I am not sure about first gear on the 2009 or if this can be helped with a sprocket change.

The fact is that I do not think much can be done on the 2010 TE250 to create a KTM stile low first. as the standard sprockets are 13/50. This gearbox is all new...

I wish they had designed the bike to use a 14 as there standard front sprocket. Must be be a weight thing Ha Ha.

I can think of lots of places where I would prefer not to slip the clutch, but do we all agree that fist is high?

Something doesn't add up, as 22/27(6th) is the same as the earlier bikes- 0.815.(not .884 as published by Husky)
1st gear is actually about 7% lower at 2.142 than the 04-09 bikes, which were 2.00 even.
Based on this, the overall spread of the internal gearing is a bit wider than prev. years, which is a step in the right direction.
According to the #'s published by Husky, the 1st 4 gears are a bit tighter than years before and the 5-6 spread is about double what it used to be(21.8% vs 11.5% before), which is what everyone's been asking for. 6th gear is now an overdrive cruising gear.

What's the primary drive gear ratio on the pre 2010 TE250's?

According to my paperwork the TE250 2010 primary gears are 54/17(3.18)

Yes primary gears are 54/17
And yes 1st is to High.
I will try 52 teeth rear sprocket to see if this helps on technical trails.

Based on my calculations, in order to get a first gear close to what the 04-09 bikes had, you'll need final gearing of approx. 4.15(13-54).

This will give this overall gearing:

2010 TXC

1. 28.26
2. 23.09
3. 19.13
4. 16.18
5. 13.74
6. 10.70

Compared to stock 2009 TXC (3.85 final 13/50)

1. 28.18
2. 23.10
3. 18.78
4. 15.28
5. 12.96
6. 11.46

Note that with a 4.15 final drive, 1st gear is almost the same overall, 2nd thru 5th on the 2010is a bit lower and 6th on the 2010 is about 6.6% higher.

If it was my bike, I'd run 13-50 (3.85) final, as I run 14-50 on my 07 TE 250 and that works good for me.

You summed that up nicely. I hate to change rear sprockets for that occasional really tight trail ride but there really isn't anything else to do.

I have tried 13-52. For me first is still to high.

I now have 12-52 which is real nice. 50 MPH on the road. Nice first gear. Changing gear on a hill from first to second keeps you in the power.

There is a flyer from Husqvarna about using a 12 tooth front sprocket.

I would like to try 54 on the back. Has anyone used this?

And finally. What gearing do they use in the Stadium Cross. Is it Zip Tye racing?
