... 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.

 

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.

 

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.
 

The 2007 Workshop Manual on JBX's site (in French) says the same too.

 

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.

 

I suggest you try 33/36.

I'm out today so I'll try the lower figure you suggest and see how it feels. I'll also look again at my figures and check my info. Thanks.

I’ve always used 37/41

I've always used 36/42, but for the life of me, I can't remember where I got that from.

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.

 

Michelin and other makers say "Use handbook pressures" or similar.

 

I assume the pressures changed when the suspension was modified - around 2005? - or after customer feedback.

I’ve always used 37/41

 

Why? Personal experience / preference?

 

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!

[Rallyist]

On the 900 I run 33 front and 38 rear on the Mk1 front is 28 rear is 35, quite happy at that.

Changed front brake pads to Ferodo sintered.

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.

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.
The Titanium bolts do look nice though.

[Studley Ramrod]

A decent manscaping session would prolly 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!!

I thought you had to be 100kg + to own a Tdm.......

Hit the gym guys, losing the cake eating habits might be a bit harder

TDM taken camping N Yorks Moors- well it is a 9er

[leehenty]

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.
