I finally took the Terra out today to see how the 15 tooth sprocket works. Well it makes a major difference in how the bike performs. With the stock 16 sprocket it was doing 65 mpg at 4000 rpm's. It now runs 65 at 4400 rpm's. It pulls in first gear without slipping the clutch and revs up quicker through the gears. I live at high altitude and the bike now performs like its a sea level bike. Really happy with the sprocket. If I was only doing off road the 14 is probably a good choice, but for my needs the bike is now pretty good
Full front and rear sprocket and chain kits here if needed. High quality and fit perfectly on my BMW XChallenge. http://www.bashplates.de/BMW-G-650-Xchallenge-Xcountry:::1:3.html
original is 16/46 as on my Pegaso I guess. changed it to 15/49 and am a very happy bad mountain roads and caminos (jeep tracks?) rider now. We don't have any freeways here, so 140km/h max. @ 6.000 rpm in 5th is not a problem :-D Have a XT250 for single track ;-)
Cant find any 15T sprocket for the 650 gs or Terra on the touratech canada site. Looking for 1 tooth down on the cs. Can you guys help me out and get me a part number, or the link where you ordered your 15T.
SS-15T. Here is the US page for you as well if the Canada site is missing other things too. http://www.touratech-usa.com/Store/3474/Husqvarna-TR650-Terra-Strada-Parts-Accessories
There is a website out there on the big WWW for gearing. It's http://www.gearingcommander.com/. I submitted the info for the Terra to add it to their data base. The website says it takes a week or so to add a new bike. They do have some Husky bikes in their data base. I loaded one of theirs in the database, and changed the gear ratios to those of the Terra. The site will calculate all kinds of stuff, but since the posts on this thread dealt with changing the front sprocket I ran three charts for a 14, 15, and stock 16 tooth front sprocket with the stock 47 on back. The attached figures show what they calculate the various speed changes and RPM changes would be. Even though the graphs say they are for a WR 300 it is really the TERRA. 16/47 is Stock, 15/47 is down one in front, 14/47 is down two in front. The stock chart seems pretty close to what I recall my speed and RPM's to be. If you want to mess around... The figure called data has the info you need to tweak things. The stock info is the info from the Shop Manual.
Nice! I generally like to change my rear sprocket to larger rather than decrease the front, but going from 16 to 15 isn't all that bad. It's like going up three teeth on the rear.
