Sherco 2006 news...4.5i & 5.1i :

Recommended Posts

http://www.motorcanario.com/deportivas/index.asp?id=6552

You better know Spanish :D

Lots of improvments in the 4.5i engine (to increase reability and power) and also in the frame (including seat height now 25mm lower).

Also, a new model, 5.1i with same bore and stroke than 525EXC...it has all improvments of the 4.5i '06.

Best pics (thanks yorkshirepud ) :

Hello Klas :D

Did you check the measures that once i asked about the front and rear disks ?

Internal diameter, bolt pattern diameter (the distance from center to center of two opposite mounting holes) and diameter of the mounting holes.

Also, can you details of how are valves adjusted in the Sherco ? (i.e. if a valve clearance goes out of spec, what is the procedure to remove old shim and to install new shim in the Sherco engine)

TIA,

AJSB

It looks like a KTM motor. Does anyone in the US know what the 450 costs?

No matter the engine looks at 1st glance the same, its not.

Sherco is making its own engine...they however, indeed seem to have reverse enginnered the KTM engine and made several (good, IMHO,) design changes like one single oil filter, damped clutch,etc.

Rear disk: Same as Husky TC ( 240 mm) Same bolt pattern.

Use the disk with no floating installation

TE have 220 mm reardisk

Front disk: I think husky also will fit. But Sherco have 270 mm disk

Husky 260 mm.

Valve adjustment: There is problem, i haven´t find any tool for that.

It also is very uncommon that you need adjust the valves.

I haven´t heard anyone needed that, Shercos valveclearence don´t change.

I have used my testbike around 40 hours.

TrailBike and Enduro Magazine (TBM) in London tested the Sherco 450i and GasGas 450FSE in the April, 2005 (number 115) issue. They gave the Sherco the win in all categories. I am considering selling my 2001 KTM 520 for the new 5.1i. Looks promising...

"That it beat the Gasser hands down in this shootout should be obvious."

TrailRider Magazine in New England, USA also tested the Sherco 450i in the July, 2005 issue. Copies can be ordered at:

Usually 4t handbooks ask for checking valve clearance at least once a year..

CR250F -05 requires it done every 30 h riding...

Sherco are maintenace free????

If it uses the same design as the KTM, the valve clearances may not move much. I had 2 KTM 520's 00 and 02. Never went out of adjustment. I know the owner of the 00 520 and he still has yet to have to adjust them. Course he rides the bike much less than I did.

I am sure though that Sherco has a maintenance period that you are supposed to abide by.

Klas, if it is a rocker on cam design the motion pro tappet set should work for adjusting:

I haven't found a rocker on cam setup that the assortment wouldn't work for.

:banghead:

Sherco use rockerarms with schims.

The schims have a small hole in the middle (not complete tru).

That conect to the valve.

Bad english.

The KTM "525" (and the "520" too) is actually 510cc as well. It's just coincidence though...

FIM mandates cc's for the classes - hence the 510

I saw specs in Sherco home page about 4.5i/5.1i '06 and its hard to believe that now the seat height is only 900mm ?!?!?

I know that they lowered it by 25mm or so, but is it now only 900mm ?!?!? a typo ?

Too good to be true !

Are there any details on the engines' features: does it run a counter balancer; is the head forced lubricated or just splash; how are the chains tensioned ? And if anyone can think of anything else.

Sherco is now on my short list.
