I don't think so. I'm pretty sure the TTRuses different axles sizes and/or spacers.

Ther rear you might be able to get away with if you use different spacers but I'm pretty sure only the TTR hub will fit the TTR.
Best bet is to hunt for a second hand set from a wrecker which is what I did when I built my motard wheels.

Are the purple / blue wheels on the older ttr the same fitting disc and wheel as the ones on my 05 ttr? I have been thinking about getting a second pair of wheels.

I certainly hope the back wheel does, Adam.
I've got one for my 2000 TTR and I'm sure it fits.
The front will fit fit - but the speedo drive may need looking at. The purple wheeled speedo is a digital thingy whereas my 2000 is a cable drive.

Supermoto Conversion (Very Easy!) - alternative wheels
Permalink  
 


I have just converted my 1997 TTR250 to a "Supermoto" .... It was relatively straightforward and CHEAP, once I figured out which wheels to use!

For the rear, I fitted a DT125X (17" x 3.5"), which more or less bolted straight on! All it required was a slight modification to the TTR wheel spacers. No extra parts were required at the rear end.

For the front, I fitted an XT125X (17" x 2.5"). Two new wheel spacers were required, plus a new brake caliper bracket(*), two spacers and two slightly longer bolts.

That's all there was to it!

Note that the spindle sizes on both of these wheels are identical to the TTR (i.e. 15mm front and 20mm rear), so I used both TTR spindles in the conversion. I got both of the wheels on Ebay!

I have attached a photo to show the results and hope you agree that it looks rather good! (although I suspect that some will regard what I have done as blasphemy!).

I am happy to give free advice to anyone who wants to do the same conversion.

Regards,

David

*Please note that I will soon be in a position to be able to supply the stainless steel brake caliper mounting plate, which I had to have specially made to enable me to fit the standard TTR caliper on the slightly larger XTX disc. It is the only complicated part required and I can have a small batch manufactured if there is likely to be any interest in them.

(By the way, while I'm on: Before anyone points out that the front brake hose should be on the INSIDE of the fork leg .... Yes, I know! That is how the bike was supplied to me, but it has now been corrected. It was by no means the only thing fitted incorrectly, either!)

Yeh think so, from eBay last week? I mAybe interested in the super moto conversion, like you say there seems to be plenty of dt and xt wheels available, what was the total cost of the conversion? Also what gearing are you using ? Adam.

I paid £180 on Ebay for the two wheels - the front one was BRAND NEW (RRP £320), complete with brake disc, for £80! I was lucky enough to get the two tyres donated by a friend, as they weren't good enough for his CCM R30! I spent a further £40 having the brake-caliper mounting plate and spacers made, but I recovered about £85 by selling the TTR wheels to domski1! I bought a new UFO front mudguard for £15 and recovered another few quid by selling the rear tyre which came on the DTX rim. The overall cost was about £140 .... so I am well-happy!

The tyres are Continental Escapes: 120/90-17 on the front and 140/70-17 on the rear. If anything, the front one is just a fraction too wide, as there is very little clearance between the forks. You may have noticed I've had to lift the gaiters out of the way! The rear tyre is just fine, but don't go too much wider than that! Actually, you could probably just about squeeze in a 150 wide, but it would be pretty close to the chain.

I have no idea about the gearing, other than it is unchanged from the ratio on the bike, as it was supplied to me (I used the same TTR rear sprocket on the DTX wheel). What I can tell you is that the effect of reducing the diameter of the rear wheel has been to gear the bike down by approximately 3%. Therefore, if you wanted to maintain the same gear ratio, you could go one or two teeth less on the rear sprocket. I didn't bother. As a result, the bike is slightly more responsive, but has a lower top-speed, as you might expect. The fuel economy seems to be unchanged, at about 24 kmpl (after correcting the figure to take account of the smaller wheel).

All in all, this was £140 very well spent. I'll be mainly using the bike on the road and it's made a BIG difference to the handling around bends. If feels much safer .... probably because it is safer! (especially in the wet!)

Nice jobsmile

 

Been fancying doing something similar, i like that idea better than getting my spare set of wheels respoked & new rims(much cheaperbiggrin ) Do yu have a note of the spacer sizes you made up?

Front Wheel Spacers

22 O/D x 15 I/D x 10.0mm Long (Left / Brake Disc Side).

22 O/D x 15 I/D x 36.0mm Long (Right Side).

 

Brake Caliper Spacers (two required)

20 O/D x 10 I/D x 5mm Thick. 

These fit between the fork leg and the replacement brake caliper mounting plate. You will also need two slightly longer bolts to mount this new plate. The size of the replacements is M10 x 1.25 (Metric Fine) x 45mm long.

guys anyone know from which else bikes i can fit the wheels? Is it posible to fit bigger wheels? like 3,5 front and 4,25 or 4,5 rear?

Wider rims would certainly fit and I did indeed consider 3.5" front and 4.25" rear. However, I don't think there is anything "off-the-shelf" that would maybe bolt straight on, with the exception of perhaps Excel rims from an XT660X.

Other than that, you always have the option of having some 36-hole rims spoked onto a set of standard TTR hubs. That was going to be my original plan .... until I worked out the cost! If you want to go down that route, I got a quote from Central Wheel Components for £250 per wheel, plus another £40 for each hub to be epoxy coated.

http://www.central-wheel.co.uk/

So that's £580, plus tyres, PLUS the cost of a spare set of hubs if you don't want to cannibalise your standard wheels.

I guess the biggest advantage of doing it that way is they would bolt straight on!

(By the way, it's a waste of time contacting Talon for the hubs, as they don't do them for the TTR.)

i am not looking for new cause they are too expensive.Also i have 4 ttr hubs :D. My plan was to keep tha same hubs and buy used wheels so i can take the rims. If i understand good ttr hubs have 36 hole right? so i must seek for used wheels with 36 holes...?!?

Correct. You wil find that most "standard" wheels have 36 spokes - especially Japanese ones .... but it's always worth checking to be sure, as some don't!

(If you buy the wheels on Ebay, you can normally count the spokes in the photo, if it's clear enough!)

punka you said that the dt125x rear wheel fitted as it was? you think the front wheel will fit also??

There is a very good chance that a DTX wheel will fit straight between the fork legs with no modifications whatsoever. Even if that is not the case, the important thing is the spindle / axle diameter. As long as it's 15mm, you can centre the wheel with just two correctly sized spacers.

Either way, you will still have to reposition the brake caliper - as I'm fairly sure that the disc is quite a bit larger on the DTX. Alternatively, it may be even easier to fit a larger caliper off a totally different bike, to give you slightly more stopping power. Both options would no doubt require a new caliper mounting plate.

Are you by any chance looking at this one?:-

no no im not going to buy from ebay!i know a guy who search for enduro wheels for his dtx so i am thinking of buying his 17" wheels... But i want them only if they fit with not many modifications...

Just ask him to check the front axle size .... If it's 15mm, it's an easy job!

Good luck!

guyzz if the front rim is 3,5 and the rear 3,5 also is there any problem? Is it good? or worse?

It's all about balance.

The "optimum" wheel rim widths are determined by many factors, including the weight of the bike + rider, plus the position of the overall centre of gravity. Ultimately, the front wheel is narrower because the front tyre is narrower and that is normally because the weight distribution is towards the rear of the bike, so a larger rear tyre is needed to get the same pressure on the road at both ends.

If you put a relatively narrow tyre at the rear (where most of the weight is), then the bike will feel "light" at the front (i.e. it will tend to understeer - to use F1 terminology).

To try and visualise this, imagine how the bike might handle if you had a giant "ball-barrow" wheel fitted at the front! Basically, you would get zero grip and cornering would be almost impossible.

Having said all of this, if you put a much narrower tyre on the front, with a wider one on the same-sized rim at the rear, then that "ball-barrow" effect will of course be much reduced.

**** i bought the rims now. The front tyre is 120/70/17 and the rear 130/70/17 but it looks much bigger.... so i must put a bigger rear?? what size should i put to balance with the front?

It all depends how hard you are going to try and push your bike through corners! If, like me, you take it easy (!),  then it really doesn't matter - You'll be fine with what you've got - espeially if they LOOK ok!

I think it will indeed look bloody good!

Furthermore, if these wheels and tyres are good enough for pushing a KLX to the limit, I guess they are equally good enough for a TTR!

Please post another photo of the bike on here, as soon as you've finished the job.

Yes, fantastic job! Now I'm jealous!

(Note to self: Get rid of that bloody purple seat-cover and fit a black one.)

Thanks! Punka yes change the seat cover! The first thing i did when i bought the bike was to paint the frame and change the cover!!! The bike looks much much better!

Luckily, mine already had the black frame (epoxy-coated) when I bought it - Someone else clearly had much more sense than Yamaha ever did! The present seat cover almost makes me puke every time I look at it!

Actually, I'm waiting to find a Raid tank and seat, before tarting the bike up a bit. I would like the extra range the bigger tank gives, but I've also been told the Raid seat is more comfortable.

I must admit, your alloy rims suit the bike much better than my black ones. I might go down that route myself at some point in the future.

i had the same problem when i was looking at the purple rims!!!i was a bit ashamed to move with the bike :P

The raid seat looks more confortable indeed.But personally i dont like the raid tank. Basically i dont like even my tank...i have plans to fit some radiator shrouds with some way!!

I was looking for black rims but i couldnt wait and i bought these! The black looks great also dont try to paint them because the paint wont last long.You must go to a shop that they paint with specific paint for alouminium..Its expensive... Except if you want us to trade them :P

Guyz the TTR measures the bikes speed from the front sprocket right?The speedometer must work as accurate as it was with the enduro wheels?

__________________

No, the speedometer reading is affected by the diameter of the rear wheel (which is geared to the front sprocket, of course).

To illustrate this argument, consider a hypothetical bike having a rear wheel the size of a 10p piece: With the small wheel rotating at the same speed as the normal enduro wheel, both bikes would register the same speed as each other, yet the "10p" bike would be barely moving. Hence, it is easy to see that the more you reduce the rear wheel diameter, the more the speedometer over-reads.

As I stated further up this page, you can eliminate this effect by fitting a rear sprocket which is slightly smaller by the same degree as the new wheel (approximately 3% for a Supermoto wheel and tyre). This equates to somewhere between one and two teeth reduction on the rear sprocket, so take your pick.

As also stated above .... I couldn't be arsed!

Punka Walla,

 

 I note in your original post that you might have had some spare caliper brackets made up. Do you have one for sale I could buy.

 

 I have the blue tank model and am looking at getting supermoto wheels so I can interchange.

 I do a lot of trail riding, but also use the TTR for commuting so the ability to change wheels is appealing.

 There are plenty of Xr125r wheels on ebay(I've been quoted £75 for a wheel including disc), but not many dt125x rears.

 Bozz

Hi Matt,

What size wheels are on your TTR?

Hi Valkman,

They are both 18 inch wheels. It is a Pirelli Sport Demon. I have two sets of rims. The other set have 100% dirt tyres. The front rim was built up from a local company.

Matt - I gather the rear is just a standard TTR rim. Who did the front 18in. rim for you as it looks great. Do you swap discs each time, or have you a complete set of both dirt and road setups.

Really like the black frame, black details and black seat. I have just got a black rear sprocket and painted the side stand black, and am thinking it could be the start of a theme throughout the bike smile

Really glad you got the purple rims changed as well.
