• 4 Stroke Husqvarna Motorcycles Made In Italy - About 1989 to 2014
     TE = 4st Enduro & TC = 4st Cross

  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

2010 TC 250 versus 2009 TXC

Are the 2010 250cc bikes with 6 speeds using similar tranny ratios as the 04-09 versions? ie. very close ratio.
Or, has Husky listened to the riders and widened them out a bit?

My 2010 TXC250 seems to have a fairly tight ratio trans. Running a 50 on the rear it does about 60 on top before it is starting to run out of breath. but then again 1st is low enough to climb anything.

The 09 and older have a lot more flywheel effect which is a big part of this.

This sounds like it can be true....Do you think a person could just swap out the flywheel between the 2 bikes and get a quicker revving TXC?

Here are the ratios from my 08 TXC250. TE, SMR , TXC all the same in my manual.

Maybe someone with a 010 manual can show their ratios here.

1st - 2.0
2nd - 1.611
3rd - 1.333
4th - 1.086
5th - 0.920
6th - 0.814

There is another thread on here with gear ratios. You also need to tell us what your primary gear ratio is, crank to clutch?
 
The primary drive ratio doesn't matter too much as it can be managed with final gearing. The more critical issue is the tranny ratios. Based on the published Husky figures for 2010, the TE/TXC tranny ratios appear to have widened out a bit(~7-8% overall according to my calcs) from 09 & earlier. It's roughly equivalent to having a 13-50 sprocket combo for the first few gears and a 14-50 combo for 6th, on the 04-09 year bikes.

If my guess is correct, using final gearing that makes the bike rev about 7000RPM in 6th at 50mph( 2010 TE/TXC) should give a decent low 1st gear for real tight stuff.

Agreed, but if the primary gear ratio is higher. Then first gear would also be higher.

You can offset the primary ratio with the final drive ratio to give the same top speed. But the gaps between each gear will be effected...

I hope that makes sense. Do the calculations on paper is best.
