Hawk 250 - Is It Ok To Just Change Rear Sprocket?

HawkTwoFifty · 10-23-2017, 09:08 AM

So I would like to do the 17/45 sprocket changes that everyone recommends to gain some top-end speed on the highway on my Hawk 250. But I am nervous about going bigger on the front sprocket in the event of a chain failure resulting in a damaged case. Probably a one-in-a-million-rare chance but I dont want to chance it.

So I was informed that I can go with a 40-tooth rear sprocket and leave the stock front sprocket in place for the same gearing result as 17/45. Does this sound accurate? And will there be any disadvantage to changing just the rear sprocket to a 40-tooth? Just wondering if there are any disadvantages since people usually change both sprockets for this change, thanks.
