front sprockets

anybody know if the front husaberg sprockets are the same as KTM ?? looking for a 13 tooth. cheers

Hi,

no the KTM ones do not fit.
13 teeth? For which model do you need it?
501?

Husaberg front sprocket

Hi,

Try Sprocket Specialties.
They have a web site that contains all the options and pricing info.
Ordered one for my bike only took a few days to get.
Realativly short money too.

Good luck,
Ryan

I have a 13 on the front on my 96 Husaberg FE501.The local shop where I usually get parts{odds and ends mostly}actually had one.The older bergs I think{I might be wrong}would interchange with a Husky.Would have to count the number of splines to make sure.Hope this helps.

I bought a 13T recently to suit pre2001 'berg & it was the same part number as a two stroke Husqvarna (ie CR or WR). The spline boss is 12mm wide & protrudes an equal amount from each side of the sprocket.

The four stroke Husky ones can be used but they are 1mm thinner across the spline boss & you have to put a shim washer in beside them or the ring the output shaft seal runs on slips out enough that its o-ring does not seal against the shaft. The boss also only protrudes from one side.

Hi,

I didn´t know about the Husky´s sprockets before. That´s a good information.
I think a 13 teeth sprocket is a bit too small for a 501 regarding to the
power of the engine and the wear and tear of the sprocket.

best regards

I run a 13-48 setup on my Husaberg FE501.I did this mainly for tight woods rideing.With this setup it can be real easy to over rev. in the lower gears.I would not run this setup on the road if anything I would gear taller.This just something I have learned when trailrideing and such,might be old age :crazy: but I always like to see what I`am fixing to get into before I do.Works fine for me.

I went to 13/52 for mustering cattle & I think I will leave it that way. Even on the road top speed is plenty fast enough without revving too hard.

While talking front sprockets, anyone know what is the largest you can fit without it hitting the swingarm, engine cases etc? I wanted to gear it up a lot to drop the revs with the motard setup.

Brad I think the biggest front I have seen is a 16.When I first got my bike it had either a 14 or a 15.I went out looking for them the other day,didn`t have any luck.I think I put them somewhere so I wouldn`t loose them and guess what happened :lol: .Hope this helps.

Yes, on 2001 and later bergs 16 teeth is the most you'll get. Mine misses the swing-arm by about .050"! 8O

sprockets

cheers guys i have ordered a 13 tooth, i find the current set up a bit high geared for the tight stuff and easy to stall out and i ain`t got no electric start.

can somebody provide an overview:

if you have eg 14-42
what will be the result
if you changed it to 13-42 or 14-45 or 14-40
so when do you need to change frontsprocket instead of the rear?
and viseversa?+
what will the result be??



more info please...

Thanx all for comments on sprocket sizes. I had a 17T 4 stroke Husky left over in my bits which I thought had no hope of fitting. I tried it last night & it will just barely go on if I modify the swingarm chain slider but the chain may tend to lick the engine case at the point where the clutch shaft fits in. A 17T sprocket with the proper 'berg centre bosses would be worse. I think you are right that 16T is about as big as you can go.



For change with respect to changing sprockets:

1. Divide the number of teeth on the rear by the number of teeth on the front for each sprocket set to be considered eg 42/14=3.000, 42/13=3.231. This is the number of turns the front sprocket makes for each turn of the rear wheel.

2. Divide the number from (1) for the set intended to be fitted to the bike by the number from (1) for those already on the bike eg 3.231/3.000=1.077. In distance this is the number of turns more (a number less than 1 means less) the front sprocket will have to rotate for the same travelled distance of the bike with the new setup. In speed this the increase in speed (a number less than 1 means decrease in engine speed) the front sprocket, and hence the engine when in the same gear, will have to spin at to travel the same road speed. This means that the engine will spin 1.077 times faster for the same road speed.

3. To work out the change in road speed with the new setup, divide 1 by the number calculated in (2) eg 1/1.077=0.929. This is the amount the road speed will decrease (a number greater than 1 means an increase in road speed) for the same engine speed.

As far as selecting sprockets to use, larger sprockets (both front & rear) will cause the chain to circulate faster (perhaps increasing wear?) but will reduce the tension or pull in the chain (perhaps decreasing wear?). Your guess on the overall effect on wear is as good as mine & I would not let that influence my choice too much.

I have not seen rears any larger than 52 teeth or smaller than 42, but they may be available. The larger the rear the more chance of it hitting rocks It also tends to wear the chain guide a bit more.

I don't think you will find a front smaller than 12T. Going this small will be hard on the chain slider around the front of the swingarm. The 13T on my bike looked barely OK. As said before, 16T is about as large as you can comfortably fit on a pre2001, don't know about later ones.

The 17T I tried came from a 17/48 I had for a long road trip on a Husky & I ended up doing much of the trip in 5th gear. I had to keep it revving due to a combination of problems.

Front Sprocket question,

2002 FS650E has 15 on the front, right ?

Should there be a "groove" on the plastic attached to the swing arm ?

For me it looked like ifront sprocket has eaten the plastic, or is it there already.

Novice thanks and over,

FinMoto

On my 2000 Berg the groove is part of the design, to clear the 15 T sprocket.

thanks Joe,

yesterday saw the 2002 FS650E and that just caught my eye .

The 17T front off the 4S Husky does work OK on the '98 model! Only just fits but. It is currently in use in motard setup. Had to trim the chain guide a bit though.
