What bend are they?


You want authentic tires look up the Duro HF308 (Pirelli MT53 style tread) and/or the Dunlop K70. Both are authentic 60s-mid70s dirt track tires, pre-Goodyear DTs. If you are running 18 front and rear the Duro has a good 4 ply 4.00-18, unfortunately their 19 is a six ply and quite stiff in the sidewall. The Dunlop has the 4.00-18 and a 3.50-19 that work great. I ended up with a Dunlp 3.50-19 and a Duro HF308 4.00-18 front and rear. I went with the Duro to see how it wears compared to the Dunlop I'd run on my SR500.

I just saw a site that showed the Tempter with spoked rims and using a 16 rear. That would make for a nice platfor to make a set of either 19s (but expensive tires) or 18s (for a better buy on tires). Maybe they're the same as the 1977 range GS spoke wheel models.

It would be nice to see more of this build. Any posts in any other threads, forums, or picture sites?

Yes, thanks. I've got about 30 hours into the pipes.

They are 7/8" Tusk T-10 YZ High Bends.

Thanks for the info. I've been thinking a lot about tires, but haven't found something I'm really in love with yet. I'll look up the tires you mention.

Originally I wanted spoked wheels so I could go with 19" rims, but the more I work with the bike, the more I like the mags. I spaced the rear subframe and fender to accommodate a 19" rim in case I ever decide to change that in the future.

First, thanks for building a REAL street tracker, not some brat bike that has fat ass tires and no suspension travel. My bet is your 650 could actually pull some decent laps on a track if you wanted to do so. That's how I'm building the SR. A flat tracker first and a streetbike second.

I originally wanted to do the Dunlop K180, the DOT legal modern flat track tread tire that was used in the 883 Sportster flat track spec series. Now those are non-existent and were not cheap to buy anyway. I do have another 19" front SR wheel and could to the 19 conversion to the rear, but the actual flat track tires are WAY expensive, not DOT legal (not that it would matter in Ohio), and really should run on a wider rim than the 2.15 on the front of the SR. The alternative would be the Duro HF308 4.00-19, but it is a SIX ply wall and is far too stiff - real popular for the Ural though.

So I looked at the alternatives. Having run short track in the early 70s I knew the tires of the day were the Dunlop K70, the Pirelli MT53, the Carlisle, and eventually the Goodyear DT. Only the K70 is available now and only in the 3.50-19 and 4.00-18. Then there is the Duro HF308 which is a copy of the MT53 tread. Duro shows a 3.50-19, 3.50-18, and a 4.00-18. I couldn't locate a 3.50-19, but the 4.00-18 and 3.50-18 are available. So the only options for the standard set ups for me were Dunlop K70 both ends or the K70 front and Duro rear.

I had run the K70s before in the early 90s, but the new tread compound and the shape of the tire had them square off rather quickly. On the old short tracker I had a Dunlop front and Pirelli rear so I figured "why not". I did the 3.50-19 front (narrower will work better on the street) and the 4.00-18 Duro rear. If I like the wear of the Duro I will consider finding an 18" RD400 front wheel which is a match for the SR cast wheel. Then I could run Duro front and rear or even run a 4.00 front and rear from either brand if I wanted.

As you can see, I spend far too much time thinking about tires. Just can't see putting the wrong era Firestones on it like all the brat guys. Those were 50s tires run on Indians and Harleys. I think the British 500s introduced the Dunlops and Pirellis to flat tracking, but probably am wrong... gotta quit thinking tires...

That was one of the original goals with the bike: flat track racing looks like a lot of fun and I wanted to give it a try so I wanted a functional racer. Unfortunately I later learned there are no operating tracks in my state (Colorado). I might have to take it ice racing instead.

In Ohio here near me they do some ice racing and riding, that was part of my thought process too. Not racing, but play racing. Been on the ice a few times and it's like the perfect flat track, very consistent when not severely rutted. Other than the cold, it's hard to beat.

She's coming along . . . still a long way to go at this point . . .

I agree they look the bomb, and why not burn both legs at the same time instead on one

This is what I drug out of a shed last fall:




I have a pair of high pipes for it - the headers at least. Here it is mocked up:



Unfortunately, they won't work with the motocross fender. So, I've got to decide between the plastic fender and the high pipes.

I've gone with the fender for now. Here's how she looks currently:
