About a year ago I went in half’s with a buddy of mine on a pair of 72 RT2s.
Almost all of the street stuff was in a box and as we went through it I noticed a difference in the front fenders, one has raised rivets and the other has what looks more like spot welds holding the brackets that the support rods bolt to.
I chose the early production bike 5/71 and his is 2/72.
I’m leaning towards the raised rivets fender being correct for my bike but I would like to be more informed.
Any info is appreciated

I'm no expert on the bigger bikes but I'm pretty sure the rivets were the earlier version and maybe the fender is even aluminum?

Hopefully somebody who knows better will come along and correct me if I'm wrong. :Buds

The spot weld fender is correct for your '72 bike. It is a steel fender and was used on 1971-1973 models. The riveted fender is aluminum and was used from 1968-1970 models.

5/71 had to be a very low serial number early production RT2?

It seems plausible to me that it could have come with the earlier riveted aluminum fender?

Hopefully not muddying the waters, but I bought an alloy fender off eBay that was marked 70 175.

The best way to tell between aluminum is to put them outside for a few years and then check for rust, aluminum will also melt at a lower temp, steel will bend easier, or if you don't have time for all that, try a magnet. :Ugh

Thanks for the reply’s everybody!
Is there somewhere on the site to look up the serial number?
Or does anyone know when Yamaha started building the 72 model year?

In the Tech Library there is a list of VIN numbers .
Your RT2 falls into a late production run , which is curious , given the production date
on the headstock sticker . I would have expected it to be an early production run bike.

100101 was first production number so wouldn't it be in the first 2100 bikes or so? (out of about 24,000 made). Probably was made in first month of production for RT2 model? Or maybe I'm reading something wrong?
