My new 300, which model is it?

[muddertrucker]

Hi, I'm going to need your guys help identifying wich model my 2011 300 is. I thought because the swingarm and rear fender have six day's written on them that it was a six days model. Now I'm starting to think I was wrong.

I know it has the cooling fins on the rear brake, ohlins rear shock renthal handlebars but no e start and no rad braces. Also the rad shrouds don't say six days and the front forks are 48mm with black tubes and gold colored caps.

Both brake discs have petals however the one on the are barely noticeable.

Thanks for your help

Which country?

Sounds like a Six Days. Maybe the shrouds and braces got damaged and that's why they are missing.

Canada, but the bike may have been imported from the states.

Makes sense the left side rad has been replaced

Mixed models across the world.

Pretty sure US six days had an Ohlins shock, and Marzocchi 45mm OC forks. In some countries they came with a 48mm Sachs OC.

Regardless, it really makes very little difference. I don't think they actually ran any variation in terms of engine, jetting, or cdi mapping. All models respond well to head work and a different needle for the carb.

Suspension is suspension. OC has its limitations on range of use, but tuners have working stacks for both.

Well i mesured the bottom tube and it's definetly a 48. I said it was a us bike because that's what the previous owner said but im realising not everything he said is true so it may come from anywhere.

How do you tell one model 48 from another?

Now on to some questions about the rear shock.

The manual says the spring in the ohlins shock is a 5.2, at 205 lbs without riding gear would i be wrong to think i need a heavier spring?

I cant see the usual clicker screw on the bottom of the shock but there is some sort of plastic wheel so i'm asuming that's the compression ajuster, am i right?

It is a Six Days they came with 48mm Sachs forks.

You can tell by looking at the fork caps. The 48mm zokes have a star shaped pfp adjuster in the cap and the legs are not black.

As far as the rear spring you probably need to go to a 5.6 or 5.8 spring rate. I am 240 and run a 6.0 spring which is still on the light side

Good info Memphis. Sure sound like 48mm Sachs to me. So many variations across geographies and models.

The stock shock spring is 5.2kg/mm. I'm only 75kgs nude, but probably over 90kgs geared up (with tools and fluids). On the 2010/11 chasis I've found 5.6kg/mm works well. On the newer linkage and chasis 5.4kg/mm.

Given this you're stock .42kg/mm fork springs will be too soft as well. .45/.46kg/mm would be better suited to the spring rates above.

My setup is quite firm though for my weight as well for those who are wondering.

The plastic disc on the bottom of the shock is the rebound adjuster. Clockwise will seat it, and then count your clicks back out. If it?s closed more than around 16 clicks you?ll notice it have a pretty substantial effect on the compression damping too though. Best approach is to go heavy enough on the spring to keep preload under 10mm. Aim for around 110-30mm sag figures (race-static).
