Oversized front sprocket safety?
SV650SF coming soon...
Now I have to address a dilemma. The stock front sprocket is a 15T, but a 16 and UP TO 17T will fit, but the 17 is very close. Now, my question is, is that 17T unsafe? In the event of a chain failure where the chain bunches up at the front sprocket and destroys the engine cases, wouldn't a huge front sprocket prevent there even being room for the chain to bunch up to begin with?
I would much prefer the 17T to the 16T as it widens my sprocket choices and reduces chain velocity(less lube slinging).
My gearing choices right now are a 16/39 or 17/41 compared to the standard 15/45. That 17/41 will put it at 4111 RPM at 70, compared to 5113 RPM for the standard bike! That is just 6 RPM higher than what a stock SV1000S would cruise at!
I definitely won't be going into 6th gear below 25 mph with the new gearing, about time I get some tall gearing! I have been in 6th gear with my CBR 250R at 9 MPH.
Edit: Even 5th gear is too tall for 25 mph, it would be around 1650 RPM. The bare minimum RPM I want to be running is 1800.
