Knock sensor or lack thereof

[TEN YC]

The DL runs an 11.3 to 1 compression ratio, while the S10 specs say it's ratio is 11.0 to 1. I believe the Suzuki is in a higher state of tune than the S10. Equivalent HP and torque in a smaller displacement engine.

The Vstrom 1000 does not have anywhere near the torque of the XT1200Z.


less horsepower as well

published hp/torque specs are: XT1200Z = 110/84, DL1000 = 98/76

But also, the dyno charts of the XT1200Z are much closer to the published specs than the Vstrom. Look at most dynos and the Strom never even reaches 70 ft lbs of torque. But the Tenere always breaks 80. Big power difference between these bikes.

Dude, every time I read this kind of stuff, it just makes it harder to wait. It was 86 degrees here today and there are so many bikes on the road.

High octane or not my first modification will be to remove the ugly fuel sticker from the beautiful tank

+1 (always my first mod)

1st mod to remove all warning stickers. don't need no stinking stickers

I'm wondering if the D mode switch would be helpful if you had to run low octane fuel. I'm not really sure what-all is changed between the setting on the switch but I'll guess that ignition timing is backed off along with a host of other things. So, if you experience detonation due to a bad tank of gas or if you are running in Mexico and they are out of Premium, simply switch into Touring mode. That seems simple enough.

Based on test rider reports of the effect of the mode switch, my bet would be that the D mode only affects the electronic throttle "cam" (i.e., the relationship between the twist grip angle and how far the butterflies open at intermediate positions between no and full throttle) and perhaps introduces some damping (i.e., preventing the butterflies open/closing too quickly).

If timing or mixture were effected that power would be down in touring mode, but all reports are that throttle response is affected but not ultimate power. I don't see any reason why they'd mess with timing or mixture if you have electronic throttles to soften throttle response.

If so, then it wouldn't have any effect on the engine's propensity to knock.

I'm just reading between the lines though. I don't know for sure.

I think that's exactly right. My 09 R1 has the D-mode switch and only changes the rate at which the throttle grip opens the solenoid controlled butterflies. There is quite a bit of difference between them on that bike.

Interesting! Is this the same two-postion mode as offered on the SuperT? I only ask since my son just bought a '10 R1 and he had not mentioned the feature (or was not aware of it).

The R1 actually has three modes, STD, A, B. It defaults back to STD whenever the key is turned off and back on. I believe the S10 will hold the last selected mode.

On the R1, STD is plenty frisky, B is probably good for rain or dodgy road surfaces and A must be for entertaining friends with wheelies cause I found it even a bit too much for the race track. It sure picks up the front wheel in a hurry in A mode though! The D-mode selector is a spring loaded switch you operate with your right thumb just to the left of the throttle. From the YAM website:

The R1 features Yamaha D-MODE (or drive mode) with rider-selectable throttle control maps to program YCC-T performance characteristics for riding conditions. The standard map is designed for optimum overall performance. The “A” mode lets the rider enjoy sportier engine response in the low- to mid-speed range, and the “B” mode offers response that is somewhat less sharp for riding situations that require especially sensitive throttle operation. Switching maps is as easy as pushing a button on the handlebar switch.

Thanks for the info!!! I talked to my son a bit about this and he confirmed he was "aware" of the feature, but had not really explored all it offered.

It is nice to have some of you experienced Yamaha riders on here to share info gained from your prior Yammy bikes!

I have some stories about seemingly interminable waiting for my 1998 R1 and my 2003 FJR to arrive, but that's another thread.
