Quote:... I notice from my TDM handbook that the recommended Yamaha tyre pressures vary with weight. 36/42 is the general figure, but lighter riders without luggage get a lower recommended figure on the TDM. ...
You must have a different handbook to me.
Â
My bike is a 2008 ABS model registered in 2009, and the handbook I have is dated 2007.9 and has the number 2B0-28199-E2 on the cover.
Â
The table on page 6-16 shows all weights to use 33psi front, with rear standard at 36 except for 90-198Kg at 42. The chainguard sticker - before it came off - said the same.
Â
The 2007 Workshop Manual on JBX's site (in French) says the same too.
Â
AFAIK the 2007 model bikes have the same suspension as mine, so the pressures should be the same for yours even if it is a 2007 build model. I've used 33/36 for everything for years, but I'm only 80Kg max. kitted up but can have a pannier load of 15Kg. No pillion. I've probably got a wee bit less than standard machine weight with the lighter 2into1 exhaust balancing the extras I have fitted.
Â
I suggest you try 33/36.

Quote:I've always used 36/42, but for the life of me, I can't remember where I got that from.
Â
Maybe the older 2004 bike handbook. AFAIK those were the original pressures given - they appear in the 2002 Workshop Manual. They still appear in some tyre fitment guides, eg Metzler.
Â
Michelin and other makers say "Use handbook pressures" or similar.
Â
I assume the pressures changed when the suspension was modified - around 2005? - or after customer feedback.
Quote:Iâve always used 37/41
Â
Why? Personal experience / preference?
Â
I don't know of any recommendation for these pressures.

No idea, must have got it from someone at a fettle day long ago! But checking my manual (first time for everything!) it says 2.25 bar front (32.6 psi) and 2.9 bar rear (42 psi) maximum, looks like I need to take some air out of the front!

I've always stuck with the Fat Bastard settings of 36/42. IIRC that's thats what the manual says for loads of 100kg+, not that I've read the manual for a few years..................

That's it. That's the setting I use - Fat Bastard. Even more appropriate after lockdown.
2004 900 - Blue with lots of goodies
2012 900 - Still adding shiny bits. Was black, changed to white and now back to black again.
You all need to go on diets it's cheaper losing a kilo or two off your waistline than spending £££ in changing all your bolts to Titanium to save the same weight.
Hey!! I'm a svelte 90 kg and concur with 34/42 ish.
EDIT....just wish more of it was on my arse for comfort!!

Took it to bits to fit a Booster Plug. Measured the unit on bench first, it's a resistor bridge I think with a clever negative coefficient NTP to compensate for temperature as far as I can make out.
