Anyone know what the top spead of a husky SM510 is? I actually have a TE510 that I SM'ed and don't have the speedo hooked up yet. Just curious what speed these things are good for. Anyone have a gearing calculator?

Took her to a sport bike track day and ran the piss out of the poor girl down the front straight. 9400rpm with 15 - 42 gearing. If I remember correctly, the TE and SM have the same tranny but can't recal what the stock gearing is on an SM. Was stable as a rock, just down on speed.

Sure was fun in the twisty bits though!!!

got mine up to 108 mph 15-42 gearing
Nice! Any idea what RPM she was turning at the time? Same gearing as mine I see. Felt sorry for my bike, after about 8-10 laps on the bike track going WFO down the sraight she started to boil pretty bad and was venting from the rad cap and the catch can. More likely due to the lack of lower rad shrouds than anything else. I figured at speed it would be getting plenty of air but guess not. Sure was fun though!

Did a track day here in texas with temps at or near 100 and had no overheating issues. ...I did replace my factory syrup for water wetter and distilled water. Not so sure you should be puking coolant in 8 laps at speed??

I saw top speed of 100 with 15/42. I was not topped out though...

well i took mine out ot fontana and on the front straight my buddy that was on a gixer was pacing me at 122, and i still had a little left, but the death wobble tends to slow things down fast. 16/42. i am also pushing 64 horses though.

I did a quick test the other day and all I had was 102, its an 08 all stock gearing.
It seams RPM limited but I wasn't looking at the tach.

I have only seen 87mph. 15/42 gearing. I kinda lost the urge for high speed when I bought the SMR. 10-40mph is much more fun. I'm thinking of dropping down to 14/42 but I commute at 60mph for 5 miles atleast twice a day and don't want it spinning too fast. I don't have a tach, so its all feel

I clocked 98 without trying too hard. Stock gearing and exhaust, and a slight headwind.
