2006 monster 620 gearing change

[POCO LOCO]

On an 06 620 monster that has already been fitted with a 14 tooth front sprocket, what would I gain or lose if I went with an increase of one or two teeth on the rear sprocket?

[stopintime]

More of the same as the 15 to 14 front sprocket. Front 15 to 14 lowers the gearing / raises the revs 6-7%. One tooth is ~2%

It will probably make the bike a little easier to ride slowly, it will feel faster and theoretically lose some top speed.

Who makes a 50 tooth rear sprocket made of steel ?

Will I have much of a first gear left if I  go with the 14t front sprocket and a 50t. rear? I have a 6 speed I might add.

5th will feel like 3rd gear!!!

I run 15/39 on my 5-speed M750.
So a 14/50 on your bike would make your 6th only a little higher than my 3rd.

What kind of riding do you do?

Back roads and highways.

15/50?  Could be a great drag bike!  Anyway, go here to play with the numbers   http://www.gearingcommander.com/

When I picked up my 620 (5spd) it came 14/45. That was waaay too low for my tastes. Anything above 70mph and is sounded like it was going to grenade at any time. Dropped the rear to 43 and it's a good compromise.
