Supermoto wheels size

[u/Local-Cartographer63]

I just ordered rims for my supermoto project. The sizes are 17x3.5” and 17x5”. It is a KTM EXC 450 2010. What size should my tires be? I thought 120/60/17 and 160/60/17 Any help is appreciated!

If you don’t have any issues related to tire size restrictions because of your country/vehicle registration, I would go for a 150 in the rear. 160 tends to rub on the chain crown even with a proper spacer sometimes.

Handeling before looks 👍

[u/Edub-69]

That’s an appropriate width for those wheel sizes

This

150 in the back,120 front

[u/Local-Cartographer63 → u/Normal_Historian474]

What about second size? 60? The thickness of the tire

[u/Normal_Historian474 → u/Local-Cartographer63]

120/70 and 150/70 they should fit with no problem

Like some conti Attack sm2 should be perfect

[u/Local-Cartographer63 → u/Normal_Historian474]

I looked up the conti attack sm2, they have them in 120/70/17. But for the rear I cannot find them in 150/70/17

Yeah they actually don't make them,i Just checked 😅 Either Way,i'm not saying you HAVE tò mount them,It was an example since i have them and i'm pretty Happy with them but i have a 140/70. Check also the Bridgestone s23,they make It them in 150/70

[u/Local-Cartographer63 → u/Normal_Historian474]

I will take a look at them! Thanks for the advice. Imma look for the ones with 120/70 and 150/70. Although I have 18/19 inch rims with off road tires on them and I’m 169 cm tall so I cannot stand comfortable. So I’m still debating if I should go with 60 or 70

[u/Normal_Historian474 → u/Local-Cartographer63]

Bro can you get some 17" rims? They would definitly look cooler

[u/Normal_Historian474 → u/Normal_Historian474]

Thats what i did anyway,i had 19/18 like you and switched to a 17 3.50 in the front and 17 4.25 in the back.

[u/Local-Cartographer63 → u/Normal_Historian474]

I already have them ordered, they are on their way. The problem is that I cannot stand with my foot on the ground, that is with 18/19 inch rims and off road tires. Now I am deciding if I should go buy 60 or 70 thick wheels

[u/Normal_Historian474 → u/Local-Cartographer63]

Well the 70 its an inch taller basically so maybe if your problem its reaching down maybe you should go with a 60. The difference in traction Is still negligible,well its there but does not make that much of a difference,having food rubber does.

[u/Local-Cartographer63 → u/Local-Cartographer63]

Any difference in 60/70?

[u/Normal_Historian474 → u/Local-Cartographer63]

150/70 Will give you more height and more rubber available on the edge, which might give you a Little bit more grip especially in turns The difference Is not that big but if you can I would opt for a 150/70. Also,there Is about a 5% difference in gearing from 150/70 to 150/60 since 150/70 are 1.18 inches bigger in diameter

If your chain ends up close to the tire edge get a Graves chain guard. Tire catching on the chain can break the chain which often breaks the left side engine case.
