The TT250 + 17T/49T = Wow!

Yep, that header above is not an exaggeration.  Gerry installed a 49T rear sprocket on my TT250 yesterday, and my reaction once I was on the road was indeed a hearty Wow!

Our TT250s come stock with a 17T/50T sprocket combination.  I know, we let a few of them get out of here with a 15T front sprocket (the 15T/50T combo is the way Zongshen shipped the first group of TT250s to us; that gear combo is for pulling stumps and climbing walls).   Our stock configuration is the 17T front sprocket with the 50T rear; that’s a good all-around approach for off-road and surface street riding.

We decided to try the rear sprocket with one less tooth (my bike’s current 17T/49T combination), and it completely changed the character of the motorcycle.   The bike pulls an indicated easy 70 mph on the freeway (indeed, on one slightly downhill stretch I saw an indicated 75 mph), and it is quite content cruising at 60 to 65 mph.  For the record, I weigh 180 lbs.  This 17T/49T sprocket setup is what I’m going to leave on my TT250.   It’s going to be perfect for the upcoming Baja run.  Oh, and one more thing…the 17T/49T combo works with the stock chain.

We’ll have the 49T sprockets available with spacers  in the very near future (the stock TT250 rear sprocket is an unusual dished arrangement, so you need the spacers).  If you want one, let us know.
