I did a top speed run on mine earlier today, and it hit 67 mph , with an accurate speed odometer. It was beyond it's optimal power range, but I never run it that speed anyway.

I live in North East Missouri so it's flat with small hills for the most part. My bike will be mostly for commuting for work . I'm about 200 pounds and all the roads here are 60 mph or less besides the interstate. Mine seems to handle it fine. I only have 170 miles on it just got it in Oct. I can't wait for spring lol

If you already have 16/45 stock then getting a 17 and 15 front to experiment wont break the bank and will likely not require any links taken out of the chain...

Rear sprockets are the more costly to change.

I'd say for most user applications 45 rear is fine.

I have a few videos on YouTube, most on my Hawk, which as I mentioned before has 16/46. I usually just run at a common sense, pace, but there is a brief speed run towards the end of this video. You may need to adjust the video quality on your end of YouTube. You can find more on my channel as well.

‘Good ol boys’ channel said he experienced a lot of “slipping” with the 15 front. Has anyone here had that problem? Your input is helping me a lot!

Probably the worst think in running a 15 with a small rear is the fact that the chain is going to be putting a lot more wear and tear on the slider. He may have meant wheel spin when he said slip, because I don't see how, it would cause the chain to slip, unless the chain was far too slack.

I didn’t think of that! You’re probably correct. I’m not worried about that. I enjoyed your ride-along video. But the audio was not great. A little garbled in places. But still fun!

That helmet fits me good, but it makes it hard to talk, because it's so snug around the jaws. I have also had a cold ontop of everything.

That’s great!
Using the 428? And how many links did you end up at?

Concidering the larger circumference of the Hawk tire, about a 40 rear, and 17 front would be about like the 37/17 on the TBR7. I am thinking that Jerry runs about a 40/17 on his Hawk. He lives in Louisiana, and is not packing the extra weight that some of us are. LOL

Hi,
I live in southeastern PA near Philly. I commute to NJ for work about 17 miles one way. Getting off the line at traffic lights was a problem as I was having to shift too soon and cars would come up close as I was not gaining speed fast enough. Went to 17/40 and the problem was solved. 5th gear is basically an overdrive so down hill I can almost pin the speedometer (It is 10% high). No vibration at highway speeds but 5th is definitely for level and slightly downhill grades. My TBR7 is stock. The higher gearing has definitely helped some of the fuel starvation problems you get with the stock carb.

I went ahead and put the full video up on YouTube. I went for gas , and then came home a different route. You also get a tour of Ripley WV. The first 10 minutes are the same as the
Coyote Run video. I plan on making one on the KPX soon, probably either on the Kanahawa River to Point Pleasant, or the TNT Area (Moth man's stomping grounds). I don't believe in any of that, but some do
