Hey I bought a 06 yz450f that had an 18" rear wheel and thought I'd do more trails riding so I wasn't too concerned. But I'm finding myself on a track more and more. From what I've read it seems like I'd only notice the tire difference if I were riding Supercross. My question is would it be worth the money to convert my rear wheel back to 19". BTW I will be riding mostly on tracks in washington. So I'll be dealing with some rain.

Doubt it. I ride both mx and woods and just went to an 18 to switch things up since I needed new wheels . Could not tell a difference and my 18" heavy duty wheel/spoke setup (most likely heavier than stock) with a starcross medium weighed the same as my stock 19 with a x30 (medium) on it. It hooks up great and I now I have more protection from rocks. The starcross is probably a lighter tire than the x30 which would explain why they weigh the same but point being there is probably more weight savings to be had in choosing a lighter tire than going to a 19" rim, if that is a concern of yours.

Nice thing about a Yamaha is that wheel fits a whole bunch of bikes so its a cheap change. Will you notice depends on  tuned into changes you are, I would notice but only if I use the same tire and different rims.
​You may notice more with a different tire than another rim.

Sweet, thanks for the responses. I will probably just run a lighter tire next time i have to replace it.

Look on eBay, 19" wheels are pretty common items. Find one for a good price, put a rotor and sprocket on it, and then you can just swap wheels for track or woods.

Around here you can typically find a good used wheel for less than lacing a new rim to the old hub. Shipping is gonna cost enough that I'd look local at first. If you don't like it, you can easily switch back.

Yeah I got the black excels so I'd have to get 19 in excel. But if I end up getting a new wheel I'll check here

I can feel the difference between the weight of a typical 18" tire and the 19's, and I don't care for the 18.  Bear in mind that between the two, there is normally no difference in tire diameter or width, just how tall the tire is off the rim.  The feel is most noticeable changing directions fast at speed, or in the air.

Did you go with the 110/100/18 or the 100/100/18. Im thinking I'll go with the 100 to save some weight. Jw if you had any recommendations, thanks

I went with the 100/100/18 but I have a 250f, I'd probably get the 110 if I had a 450 since that is what comes on them and what everyone seems to run. I had good luck with my x30, i think rockymountain has a $40 promo going on them now. Starcross 5 medium seems to be pretty good too, time will tell on it's durability.

Missed the part you ask about weight, I'd probably go for the starcross then between those two.

 

check out this thread:

 

http://www.thumperta...h-their-weight/

 

For example the 110/90/19 maxxis it is 12.9lb while the 110/100/18 is 14.2lb. so 1.3lb more for the 18

 

Yet for 110/90/19's the tire weight ranges from 10.4-14lb so there is a pretty big variance depending on brand/type of tire. You can also save a bit of weight going with a regular tube instead of a heavy duty. Those heavy duty tubes are pretty damned heavy. Also michelin advertises the new starcross 5 as 15% lighter than the previous starcross 3/4 (MS3 and MH3 i think??
