I'll be changing the front sprocket later today and was wondering if anyone knows how much torque to use?

Hi,
it's 120 Nm.

Thanks!

So, I finally got to change the front sprocket. 14T down from 15.

I dunno.. Maybe I was expecting too much, but I can't say I notice all that much of a difference. My motivation for changing it was making it go slower in first and second gear, making offroad a bit easier on the clutch and such (hey rhyme!). I guess it must go a bit slower, but my initial test driving around the parking lot wasn't all that great.

It did however feel a bit friskier going from 20-100 km/h

And now a question - Where does the bike get its speed reading from? Before changing the sprocket I was going somewhere around 105-110 km/h at 4000 rpm. With the new sprocket, it's more or less exactly the same?

Gearbox output shaft, so nothing you do will change the ratio between indicated speed and rpm. You aren't doing the same real speed as before though.

5'ish hour highway haul today, and yeah... I'm NOT doing the same speeds as before
I brought a GPS along and it seems like I'm roughly 15 km/h lower than indicated on the speedo.

Since 1st and 2nd gear aren't as slow as I was hoping for, I'm kind of regretting changing the sprocket. Those 5 highway hours were tiresome. 5k+ rpm all the way. Nonstop rain didn't help, though. Hopefully the offroad trip planned for this weekend will make up for it!
