Power restriction in first 3 gears now lifted

[Blue_eyes]

A German Yamaha dealership has found a way to lift the electronic power restriction in the first three gears.

Cost is around EU 620,- (approx. US$ 875,-).

Google translate (with some corrections from me):

Since the beginning of September we now have a Super Ténéré with full power delivery in all gears. As many XT drivers know, the machine's performance is by default electronically limited in the first 3 gears. Now we have lifted that electronic barrier, which results in an extraordinary gain in the fun of driving. When touring in the Alps or on small country roads it means a large increase in performance because these are the area's where you drive in the lower gears.

Customers who have already experienced:

Mr. S.: "Wow, that's a completely new motorcycle!"

Mr. J.: "Finally I have a Ténéré without mothering.

Mr. T.: "I was already convinced after the first few miles and thought to myself - this must also be in my Ténéré!"



Therefore, our recommendation to schedule a test drive appointment and experience the new Ténéré feel yourself!

Oh no! Something else to save up for. ::015::

LOL, "paternalism"? Mothering maybe?

Here we go! Wheelies and bald rear tires. Yeehaa!

Destroyed final transmission???

Wouldn't that have the Starbucks BMW crowd whipped into a frenzy? They'd be trading off buying rounds of latte. I'm hopeing Yamaha limited the power to save people from themselves with TCS switched off. I'm thinking the final drive will be just fine.

Re: Power limitation in first 3 gears now lifted

Man, you may be right and I definately don't want to make the BMW Starbuck's crowd gloat, but I'm an engineer and it is my curse to think that way. Who knows what derating calcs Yamaha applied to the final transmission. Personally thinking it's a good idea, albeit very cautious, to wait and see if the PCV and unrestricted mob run into issues. Their pain, my gain, so to speak...

Re: Power limitation in first 3 gears now lifted

Yamaha has a reputation for building drive shafts. The FJR1300 has one that takes 150 HP and 135 Nm thrusting forward a 291 kg bike plus driver and passenger and luggage....

I would be suprised if the drive shaft of the Super Tenere is any different than the FJR1300's....

Anyway, I am not worried about the life expectancy of the drive shaft. The sole reason of Yamaha for limiting the torque in lower gears was drivability.

The V-Max is a huge, heavy, hp and torque rich shaft drive machine without a history of shaft drive problems. So yeah, I'm pretty sure Y knows the design concerns of shaft driven motorcycles.

Re: Power limitation in first 3 gears now lifted

As background, its pretty common for big bikes these days to have power limitations in the lower gears. It's usually for controlability reasons as mentioned. The rationale is that it is stupid to have a bike make more power than it can put to the ground and in the lower gears, you can only put so much power down before you either get wheelspin or a wheelie. My S1000RR limits power in the three lower gears to about 120, 135, and 150 RWHP. (This has the interesting side-effect of meaning that I'll never experience the full 180 RWHP of my bike unless I'm doing over 140 mph, the speed required in 4th to hit the engine's power peak.)

However, the S10, with about 90 RWHP, is hardly a rip-snorter like a liter sportbike, so I'm a little surprised Yamaha did this. This may be another reason that so many testers complain that the S10 seems "less playful" than the R1200GS. I would think any decent rider would be able to put a full 90 RWHP down in the lower gears and assuming a reasonable body position, not have issues with wheelies or wheelspin. If Yamaha did this for controlability reasons, they're being extremely conservative. Perhaps it has something to do with the TC system.

Re: Power limitation in first 3 gears now lifted

Ive been told that the ST has 200Hp V-max parts in it.. As others have also said, the 145Hp FJR is bullet proof... Taking off the reduced power from 1-3 will have no effect on the drive train. IMOP, its the over all usability of the power on and off road. They tried to tailor the power for what the bike was meant to be used for.. Not a R1 race bike...

I don't think the TCS abilities will have anything to do with it (as if the system would get overloaded by continuous wheelspin). Yamaha has always had one goal in mind, making a superior bike by making it handle better (lower center of gravity) and more controllable (see the ad's where yamaha compares the XT1200Z with the BMW and Mutistrada).
And we have the option to switch off the TCS. With the TCS switched off, it is a totally other bike. Try it.

Riders who drove the BMW R1200GS and the XT1200Z side by side will tell you that both bikes accellerate just as fast. Only when reaching (from + 180 km/h (110 mp/h)) top speed the BMW is able to walk away slowly. What makes the XT1200Z -seem- less playful is due to it's powercurve, it is flatlined, so it does not give an extra punch in the rev range. It is perception that fools us to believe the XT1200Z is the tamer bike. It isn't, is just the way it outputs it's power not the amount.

I will call the German dealership tomorrow to find out what they did and how, and will let you know their answers here.

Mine snaps wheelies quite easily in first, second needs a hump for a snap wheelie, but standup second gear wheelies are not a problem, as is third gear with a hump. And just to be clear, this is without smacking the clutch.

However, the price for the "cure" is quite steep at the current price.

It's a real shame that Yamaha didnt release the S10 with an honest 120 rwhp motor...it would have been "all" that I am looking for in the bike.

Rumours are that Yamaha will release a 130 HP version.... maybe to combat BMW's announced 2012 watercooled version of the R1200 GS and KTM's announced 1200 allroad version...? :question:

Re: Power limitation in first 3 gears now lifted

Looks like you could remove the restrictions with tune boy or power commander and a trip to the dyno. Which would put you in that same price bracket.

Re: Power limitation in first 3 gears now lifted

For fun im going to look into that with the PCV.. you can change parameters per gear.. Im sure with enough time we could document what is going on in each gear and make appropriate tunes per each one. What are they doing to 'take off' the restrictions ? Are you buying a new ECM ? Is it a piggy back unit they sell you? Are they mod'ing the factory unit? Etc ??????? Anyone know yet ? Where these a will, there's a way.........

That's exactly what I plan to find out when I give them a call tomorrow! Including what the power output is in each gear, if possible with some proof eg dyno run graphs.

@ Snuffcityrider: A PC V does not lift any restrictions. I have one and I already asked my tuner who is the importer for Dynojet in EMEA. Or, you can call Dynojet yourself, they are helpful.

Re: Power limitation in first 3 gears now lifted

Not sure how all the PC stuff works. But I do remember guys on the Rocket lll site importing maps from Tune Boy into their PC's to remove restrictions. The Triumph Rocket was also limited in the first three gears. I went with a bud of mine to watch his R1 tuned on the dyno with a Power Commander and they were able to do away with the rev limiter or at least move it higher. This was done at Stadium Yamaha in Dallas. So I believe it can be done, but maybe not with a PC alone.
