The size ratio between the front and rear sprockets affects a motorcycle's acceleration and top speed. A larger rear sprocket or smaller front sprocket will increase acceleration but reduce top speed. Conversely, a smaller rear sprocket or larger front sprocket will increase top speed but reduce acceleration.

00:00 Welcome to DriveSpark, I'm Vedant Johari and we are at NMW Racing today to talk about chain
00:11 sprockets and not your rear chain sprocket but the front chain sprocket.
00:16 So what I have in front of me is an Interceptor 650, no it's not a 650, this is an 865cc
00:23 Interceptor, big board at NMW Racing and it produces unbelievable amounts of torque.
00:31 Right from the get-go, she wants to get the front wheel in the air, it's very hard to
00:36 keep her on the ground.
00:37 So now we can talk about the chain sprockets.
00:41 So as most of you already know, we change the rear chain sprocket for performance changes
00:47 to either get more power or to offer reduced power and a better top end, but did you guys
00:54 know you can also change your front chain sprocket and on the Interceptor that is located
00:58 right here.
01:00 So now this is the stock chain sprocket that we get on the Interceptor, this is a 15 tooth
01:06 chain sprocket.
01:07 Now with the stock chain sprocket on this, the bike was almost unmanageable in the cities,
01:14 if you drop a gear and give it throttle, the front wheel will 100% go in the air.
01:19 So now to tackle that, to make it much more rideable and to give it a little more top
01:23 end speed, what we've done is we've changed this to a 16 tooth chain sprocket.
01:29 Now the 16 tooth chain sprocket, if you go for a bigger size front sprocket, that gives
01:34 us better top end and less torque.
01:37 So it takes away a little from the acceleration, but whatever little is gone from the acceleration
01:42 is added on to your top speed.
01:44 So this bike could clock around 210 km/hr on GPS on roads, but now with this added larger
01:52 chain sprocket, we can expect speeds for above 215 km/hr now.
01:57 So if you go for a 14 tooth front sprocket for example, that would increase our torque
02:01 even more.
02:02 So smaller front sprockets are normally seen on drag motorcycles and in events where you
02:07 just need acceleration.
02:09 Now larger front chain sprockets are seen where top end plays a massive role.
02:14 For example, if you're doing a top end run to see whose bike is faster or if you're riding
02:20 it on a fast circuit, then you'll need a larger front chain sprocket.
02:24 Now the good thing about changing your front sprocket and changing your rear sprocket is
02:28 that you don't need to change your chain.
02:30 You can keep the stock chain, you can keep the stock links, you don't need to remove
02:33 any links and it'll still fit on.
02:36 However, if you change your rear sprocket, that's not the issue.
02:40 Changing the rear sprocket means you'll need to change your chain or remove a few links
02:43 or add a few links to your chain.
02:45 So that was the difference between a front chain sprocket and a rear chain sprocket and
02:50 the different sizes, what they do for your motorcycle.
