Anybody try fitting a 120/80-16 to the rear of a 2012 DS?
I'm looking at an Avon AM26
-
I am going to put on a 120/90-16 on my DS next week. Going with this tire:
http://www.motorcycle-superstore.com/2/29/393/14732/ITEM/Bridgestone-TW40-Trail-Wing-Dual-Sport-Rear-Tire.aspx (http://www.motorcycle-superstore.com/2/29/393/14732/ITEM/Bridgestone-TW40-Trail-Wing-Dual-Sport-Rear-Tire.aspx)
Not a lot of good choices for that stupid 16" rear rim.
I think it will fit no problem, there is plenty of clearance.
I would be curious to know what others have been using for replacement tires. My rear is not going to make 3K miles, just melted away.
-
Ah haa.. Curiously i am too looking for replacing tires on my DS 2011 and to get the 16 and 17" tire the same brand and type and model it is pretty difficult !!
I want a low profile wich is not easy... i am looking for 70 profile on rear
Here is my best choice from now:
Kenda Cruiser K671
Rear: 140/70P-16
Front: 110/80H-17
The new rear tire should give me 30 more mm width for a better look.
Or Pirelli Sport Demon
Rear: 130/70 - 16 M/C 61P TL
Front: 110/80 - 17 M/C 57H TL
Or Shinko 006 Podium
Rear: 130/70 - 16
Front: 110/70 - 17
I have measured the clearance between the tire and the belt and i have 22mm. The other side have pretty much.
so theoricly i could add 40mm and get a 150mm on rear but again finding a brand and model that have 17 inch tire that match is pretty difficult too!
Do you know if it is really necessary to have the exact same tire model on fronta and rear ? If not the choice are alot more interesting !

You're going to want a lot more clearance than you'd think. It's amazing how much tires move around under stress and heat.
As far as looks go, if there was ever a situation where form should follow function, it's in tires.

Please let us know how it fits. That's an extremely agressive tread. I'm hoping that going to a street tread smooths it out a little.
Looking at the clearance, I'm amazed that a 17 won't lace up with no cutting of the swingarm. I may try that route this winter.

There was a Thread http://electricmotorcycleforum.com/boards/index.php?topic=2127.msg8035#msg8035 (http://electricmotorcycleforum.com/boards/index.php?topic=2127.msg8035#msg8035)
I have an appointment next Friday at the TÃœV because I will run a 120/80 -R16 on my 2012 DS and I need to change it in the paper, if not I run in trouble with police or the all 2 years TÃœV examination ???
If my calculation is correct the speed will be 1% lower so it should not bother and is like normal profile tolerance. (We have the law the speedometer has to show a faster but never a lower speed.)
-
You can recalibrate the spedometer easy ;)
there is some info on the forum to acheive that

I seem to be the only DS rider who rides a lot of dirt. I have to have some tires with some bite as all of my rides start and end with 3 miles of dirt road. Just last week I got caught in the downpour and rode home in the mud so street tires are not a good option for my riding requirements.
I think I will put a rear tire of the same tread on the front when that one wears out... there is no good front specific match. I have been told that it is OK to put a rear tire on the front but not a front on the rear.
Another reason to lust after a 2013: standard tire sizes.
Trikester fitted a 17" rim on his 2012 DS. It was not trivial. There is a post on this forum about that modification.

Here is what my OEM rear tire looks like after only 2600 miles:

These tires are really soft rubber.

I had the same "problem" at 2200 miles, than I tried to find a 110/90 what was not so easy. I got a Michelin M45 110/90-16 but it is gone in 1500 miles :o

I couldn't find a dirt tire at all, but I use the bike most on paved roads and look for a street tire.
My choice:
Michelin City Grip Rear 120/80-R16
Hope the rear last longer because it has no tread in the middle.http://www.motorradreifendirekt.de/cgi-bin/rshop.pl?details=Ordern&typ=D-112964&cart_id=24622743.1100.16781&Cookie=&ranzahl=1&Breite=120&Herst=&Quer=80&Felge=16&Load=&S_Z=-&Speed=&weiter=0&last_sort=&kategorie=&Ang_pro_Seite=10&sort_by=&gesanzeige=&rf=&Transport=P&tyre_for=&F_F=&dsco=1100&sowigan=&RunFlat=&m_s=1&profil=&Achse=&LoadRange=&s_p=&x_tyre_for=&rsmFahrzeugart= (http://www.motorradreifendirekt.de/cgi-bin/rshop.pl?details=Ordern&typ=D-112964&cart_id=24622743.1100.16781&Cookie=&ranzahl=1&Breite=120&Herst=&Quer=80&Felge=16&Load=&S_Z=-&Speed=&weiter=0&last_sort=&kategorie=&Ang_pro_Seite=10&sort_by=&gesanzeige=&rf=&Transport=P&tyre_for=&F_F=&dsco=1100&sowigan=&RunFlat=&m_s=1&profil=&Achse=&LoadRange=&s_p=&x_tyre_for=&rsmFahrzeugart=)

I think the constant torque will really wear out more than one think, and even if the bike don't feel so nippy because power is not raising up suddenly like an ICE it has steady torque in both direction.
Sorry for the long links!
-
I might order the Kenda cruiser K671
Rear: 140/70-16
Front: 110/80h/17
about 150$ for both.
I will let you know if it's a succes

Nice tire,
I just looked to the specs: (Thanks to protomech)
the DS 2011 front rim is a 2.15x17, the DS 2012 is 2.50x17 both use 100/80 17,
The S 2012 has a 3.00X17 for a 110/70 17.
Don't you think a 2.15 is a bit slim for 110/80?
I have only little experience with rims and tires, also I was thinking of a 110 Front wheel but it is really tight at the DS-fork. I know with your add batteries the fork will set lower, but if I accelerate my fork "come off" again.

FWIW RickSteeb installed AM26's on his 2012 DS for street tires last year: http://electricmotorcycleforum.com/boards/index.php?topic=2127.msg7468#msg7468 (http://electricmotorcycleforum.com/boards/index.php?topic=2127.msg7468#msg7468)

I searched and completely missed that. Exactly what I wanted to know! Thanks much.

OK, I seem to be in the minority here as I ride my DS in a lot of dirt. As such, I was really disappointed in my tire options but after more research I went with a 120/90-16 Rear Bridgestone Trailwing TW40. Good news, it all fits if anyone else wants to go that route you can do so with confidence as there is plenty of room for that size of tire. I will report back if there are any negative impacts on range or power but it does fit just fine as you can see from the pics below.
Looking forward to having a little more bite into the soft stuff and sand.

There is not a front that can match this tire in a 17 so I am probably going to mount another rear tire on the front wheel when it is time.
-
Nice Tire!
good info, I had never believed a 120/90 will fit so easy :)
-
Ordered the Avons today. Can't wait. Anyone want a set of stock knobblies cheap? <400 miles.
-
I really like how the new tire grips in the loose stuff but there is a problem: I now have some vibration and motor unsmoothness at certain speeds. It is most noticeable at around 15 MPH. I feel some vibration in the foot pegs which I have never felt before the tire swap. At first I thought that it was just the knobs on this new tire but now I believe it to be related to the motor in some way.
Could changing the rear tire size affect the motor feedback loop someway? Where does the Zero get it's speed data from for the speedometer and is that fed back into the servo loop somewhere?
After changing to a larger diameter rear tire I now have some roughness in my Zero motor's operation. It is worse at right around 15 MPH.

This morning I just read some complaints about some street-legal off-road tires having vibrations at certain road speeds on a BMW GS forum that I frequent. So it might be the tire. Perhaps the thing to try is to let the bike roll down a hill with the ignition off and see if you notice the vibration. That should tell you if it is from the tire or the drive train.
-

Technical I don't think so!

The Sevcon tells the RPM it has also some calculation from Rotation to speed, but I don't know how Zero use it. I know that you can change the speedometer ratio, maybe Zero do some other calculation :-\
The Sensor for rotation (Sin/Cos encoder) is located at the motor, it is the plug at the left side Encoder + Temp sensor.
So your tire shouldn't have an effect to the encoder.
Do you really think it isn't the tire? Maybe you suffer of "German Angst" :)
-
Hey Richard and BSD,
Thanks for the responses.
I will try the downhill roll test later today... I know just the spot for this test.
"Greman angst?" LOL. The first day I had myself convinced that it was just the tire but on the ride in today I was sure it was the motor.
More later.
-
When I first got mine the dealer had the pressures set at 27/27. The vibration starting at about 45 mph made the bike almost unrideable. I pumped them up to 32/35 and most of it went away. I'm hoping that the conversion to Avons gets rid of the last of it.
-
As Richard suggested I shut off the key and coasted down hill, no power. Sure enough, the vibration happened right around 15 MPH so it must be the tire. Thanks for the suggestion Richard. I will experiment more with tire pressure, right now at 32 PSI front and rear.
Must just be that "German Angst" as diagnosed by BSDThw. : )
-
Also Make sure the tire are balanced, exrea weights added to the rim, offroad tires can be very unbalanced.
-
My guess is that the problem won't be solved by balancing the tire. A tire out of balance will tend to hop up and down and will get worse the faster you go. A vibration, especially one that only occurs at certain speeds, is most likely a characteristic of the tire's tread design that you may just have to live with. Obviously you should make sure that the wheel is balanced, but I can't think of anything else you could do, other than adjusting air pressure, that might reduce the vibration that you feel. And it is better to have air pressure set to provide you with the best on- or off- road performance, than one that just reduces the vibration. But it never hurts to experiment and the important thing is that your fears of mechanical problems are resolved. :)

I do not know if to laugh or cry!
I have an appointment next Friday at the TÃœV because I will run a 120/80 -R16 on my 2012 DS and I need to change it in the paper, if not I run in trouble with police or the all 2 years TÃœV examination ???
Today I have had my date, but it turned out in the wrong way!
We all know a 120/80-R16 fits well, so the TÃœV inspector could see there is plenty space. Then he was asking his computer and it went out a 120/80-R16 standard rim is 2.75x16 and my 3.00x16 is to WIDE for this tire :o actually a 110/90 shouldn't be on that rim at all ???
Of course the inspector knows that a 120/80 will run pretty good at this rim but now I need a "tire approval" from Michelin using a 3.00x16 rim for a 120/80 City Grip :'(
Why is life so complicate in Germany
-
The Germans do love their rules and regulations. ;) It all started with the Prussians, I believe. ::)
I think it all started when the Prussians started putting spikes on their military helmets. :o
-
always wondered about that spike, obviously would stop Germans sitting on there helmets, would have been a nightmare for stores and shipping , lol
-
The Germans do love their rules and regulations.
they really do go overboard over there, though. and i thought new jersey was a police state. they have nothing on germany. viel glueck mit Michelin.
-

Hi Richard nice try to tease me but I am from Bavaria and Prussians and Bavaria tease each other also, therefore I 100% agree with you ;D
viel glueck mit Michelin.
Yes I am not sure how cooperatively Michelin is, They have a Contact Form for this, I did sent; see what will happen.
I have to add, the Inspector is nice and helpful I do run the tire now and if police stop me I shell tell them to contact him, so I should not run in trouble ;) Instead of using my old one with a tread under 1,6mm!
-
Christmas in May
-
Today I got an email from Michelin Germany confirming to use the 120/80-R16 City Grip on our 3.00x16 rim.
Hope this will satisfy my inspector. If someone has the same problem PM me and I can forward the email!
nicktulloh have fun riding your street tires. I have mine now for 250Km and the front tire feels much better.
-
Put the Avon on the front today, ran out of time to do the rear. Went out for a ride and the bike is absolutely transformed. I highly recommend this for anyone still running on stock tires and not riding any dirt. Much, much smoother and ALL of the mid-50s vibration has completely gone.
Can't wait to get the rear on.

There is not a front that can match this tire in a 17 so I am probably going to mount another rear tire on the front wheel when it is time.
I wonder what a second set of wheels & rotors would set one back, to make an easy swap between [uncompromising] street & dirt tires. I mainly use my DS for daily highway commuting, but would love to take it on some nice cow / fire / goat trails once in a while!
-
I asked my dealer for the price of the S wheels, it was an idea to change it to my DS for better tire range. Didn't get a price yet.
But be careful I am not sure if a 110/70 will fit between the fork seals part. It at a different position (tire) at the DS!

I will try the K671 with 110 on the front and will give you the confirmation. I measured like 8mm clearance on one side and 10mm on the other side with the actual 17/90-100 ds tire so with 10 more mm total it should be like 5mm more on each side so this will leave 3mm clearance. But even it it dont fit i could readjust the spoke to shift a little bit the front wheel by 2-3mm if needed. As for the rear 140 tire same K671 serie from Kenda, i'm pretty sure it will fit nicely.
installation is schedule on 6 june.

Windrider who's that new back tire working out for u I am thinking about one?
-
Soup,
I like it. It definitely hooks up better in the loose stuff. There is a little vibration around 15 MPH. Other than that, better on pavement as well.
I am going with the same tire in the front soon as the the front OEM tire is getting thin.
-
Thanks WindRider I did not buy my bike for all street 20 dirt 80 if I could get knobs that is what I would run thanks again Soup
-
I agree, I put the Bridgestone TW40, 120/80 on the back of my DS recently, its great, only a little low speed vibration, like rolling too a stop. I got 3500 miles per tire out of the two previous stock rear tires. This tire has deeper and a little more aggressive tread. Looks good also. The stock front tire is still holding up.
