45 Tooth Rear Sprocket

This sprocket is a direct replacement for the original, except that it has 45 teeth instead of 47. Installing this sprocket will effectively reduce the number of engine revs needed to move you down the road at any given speed. You'll therefore experience less engine vibration and realize better fuel economy. Combining this 45 tooth rear sprocket with a 17 tooth front sprocket will provide yet a longer ratio. These sprockets are a high quality product, made of tough steel in the "Diamond-Cut" procedure.

We also have 14,15,16 and 17 tooth front sprocket available. See Under the Related Products.

I ordered both the 45t and the 18t sprockets as recommended by Wunderlich. The quality is great, the fit was perfect, and the highway ride is now actually relaxing.

I decided to order sprockets from wunderlich because I wanted a top quality part for my 04 bmw dakar. Instead I received an after market front and rear sprocket from JT, which previously I had discarted from my preference, even when these were half of the price and included free shipping from amazon and eBay . The description does not say that will be a wurderlich part but is assumable, nor says that is a JT part. Which in this case I would had not purchased it from wunderlich at their price PLUS shipping. Next time (if) I have to order an item from them I will have to check first what will they ship to me? Not to happy actually disappointed . The sprockets are doing their job for now, bike is running at a lower RPM at Hwy speed (75mh) but I am concern about the lasting of them since the reviews in other webs are not the best.

Brought the rpm's down at highway speeds, much less vibration. Runs very smooth at 70 mph. Great product!

45 tooth sprocket brought the revs from 5000 at 75mph to 4500 and the difference is a pleasant surprise. It feels like a less taxing ride at higher speeds. Only thing is I can't lug it in 2nd making a tight right. Not a big deal. Quality seems good. Fits well. It really altered the nature of the bike at highway speed for the better.

An excellent upgrade.

I installed this sprocket on my 2006 Dakar last weekend. I was looking to reduce my rpm at highways speeds. The job went well and I couldn't be happier. Sprocket fits perfect and works great. Good quality. I dropped my rpm by approx. 400 at 65mph. Power loss at lower speeds is negligible. I would definitely recommend this for any F650 GS owner who has to do a lot of highway miles in between the dirt.
