Sprocket plus/minus one tooth ?

What’s this all about?

If your front sprocket has one less tooth, does it mean you get more acceleration but less torque? Or something like that?

Anyone remember a band called Toad The Wet Sprocket? They were featured on a few compilation albums from the NWOBHM days. Did they have less teeth than the other bands of the time?

power and torque are not affected…

one less tooth on the front will give you faster acceleration but you will also need to change gear sooner or rather at a lower speed.

its a good cheap mod for a bit more poke, or to feel like you have a bit more poke :slight_smile:

Cheers for that… a bit more poke is always useful!

Metal for Muthas Vol 1! ahhh memories!!

Screaming down the motorway at 9000 revs for hours is no so useful though, so be careful how much you change and bear in mind how you use the bike.

Anglewitch - “Baphomet” … shivers down my spine just sitting here thinking about it! That was my favourite of all of those bands that never really made it. Saw them loads in 1980-84. I met the singer Kev in a pub in Beckenham about 10 years later and he told me his ‘version of events’ as to why they weren’t promoted well enough by Bronze Records.

Cheers Alex, but no motorway for me on my slow-but-trusty Z200! I’m sure my arms and legs would fall off from the vibrations at any speed above 45mph.

is this the sprocket at the engine or wheel end?

Front

Engine = front, wheel = rear.

d’oh. that’ll teach me to read the OP too fast

Jay did you go 1 tooth down on the rear sprocket of your 1000? 1st gear is super tall.

Though, the bike revs so quickly that I was always think I have more gears to get through when in 6th.

It’s lovely power :smiley:

You missing it yet? :wink:

I was -1 on the front and +2 on the rear with my thou. It accelerated like a rocket :slight_smile: Amazing, absolutely amazing when you wanted to leave someone for dust. And yes, I do miss that experience! But horses for courses and all, and I love the 750 for being more nimble and easier to throw around!

technically speaking isn’t this only true of the engine? (i’m part asking as i’m not 100% on this)

if you have one less tooth on the front engine mounted sprocket its smaller so for a given rpm it exerts a proportionately larger turning force on the rear wheel - i.e. there is greater torque over the rear wheel?

or does this get us into ‘torque’ vs ‘work’?

More torque at the wheel, yes. This is the principle of gearing, altering the speed and turning-force (torque) of the wheel.

Sheet. I thought all of those had long gone to the great breaker in the sky.

Had one of those as a refresh bike after a lay off back in 1977. Loved the little bugger once I’d changed the plastic tyres for some decent rubber and the pads for something not made of old lino.

I’d keep the front sprocket as standard and drop a tooth or two off the rear. A bit less dramatic.

If you drop teeth off the rear, you’ll lengthen the gearing, i.e. make it slower to accelerate, but perhaps add more top end speed (if you have enough power to overcome the drag).

Jay Your right, of course.

Should have read “ADD a tooth or two to the rear sprocket…”
