Title: Gearing options...
Post by badwolf on 09/02/20 at 11:59:31

We on the Savage have gearing options, limited, but some. First we can change the size of the rear tire, simple but limited.

Second we can put on a larger front belt drive pulley, many folks do this and most are happy with the higher overall gearing.

Third in combination with the larger front pulley, we can use a smaller rear pulley. This gives you a much higher final drive ( 2.6 to 1 compared to 2.98 to 1 stock ). My fav!
BUT, it makes the stock speedo basicly useless, and is high enough that starting off uphill with a passenger is,,, well, a challange.
The speedo can be overcome with a GPS unit, and the other thing, well, just put on a solo seat and move down here to Florida where we have no hills!  

Fourth you can go with a chain conversion and have a wide choice of final drive options. Along with the joy of chain maintance and filth.

There is really no option, that I have heard of, to go internal and change the gear raitos in the tranny. ( If someone has done that please post your results. )

Now to the point of this post. This link will take you to a clip about motogp gearing.

This guy really knows what he is talking about and the options they have will blow your mind!
They can change-
final drive ratios
primary drive ratios
internal tranny gear ratios, one or more or all!
And they do this not just for rider preferences, but to suit different corners of each track!
And check out the shifters, they are linked to a pressure switch to blip the ignition when shifting, insted of the rider clutching or bliping the throtle for moto2 and moto3.
The top motogp bikes have a even better system they keep secret! ( but the riders don't touch the clutch unless starting or stoping )

I love my bike, primitve as it is. All this new hi-tech stuff is fine if you live for performance, ( cubic dollars, as the drag racers say )
I just want to cruise.
When I was at the salt flats in 18' one of the popular classes for the bikes was the 250 cc pushrod classes, and they haven't been made for decades!

I do believe the primary gears on the 4 speed bikes was made a taller ratio when the bike was made as a 5 speed (I don't have the tooth count numbers memorized).

This doesn't help the 5 speed folks - but if you have a 4 speed bike you can install a 5 speed crankshaft gear and matching clutch basket and reduce the engine rpm a small amount and get a bit.

Yeah, but the difference between 4th and 5th on our 5-speeds is pretty minimal.  I have a 5-speed, the bigger front pulley and a bigger rear tire but it still seems like pretty high RPM's for anything above 65 mph for long stretches of highway.  And taking off from 1st gear is kinda lame now. :-/

Dave, I maybe wrong but I think the changed the primary ratio in the later part of '86 or '87.
Very few clutch baskets have the larger gear as some said you can take off the primary w/out removing the clutch basket.

Seem like quite a few want to gear up.
But I want to gear down and retain the belt.
I need short lagga not super legga gearing.
No on seems to have a answer to this one.

You could go with a smaller rear tire, BUT you might have to get into scooter tires. Some are rated for 93 mph, but if your buddies found out you would never live it down.
Maybe Dave might know of a 22 tooth pulley that would fit?

You're living in the stone age. Modern o-ring and x-ring chains require little to no maintenance at all...and that includes lubrication. An annual cleaning is all I do on all of my bikes.

My buddies don't care,
Hey I ride a Puch 250 sgs with 16 inch wheels.

They do. Around 40,000 miles or so.

I am about to turn 110,000 miles and still on the orignal belt.  Same Kaw pulleys I put on at 9,000 miles.
My three previous bikes were shaft drive.
I'll just stick with chains on my bicycle.

The split single is very touqy , just not a lot of speed. So I am trying to build my ryca conversion into it's replacement. Most of my riding on the back roads with the Puch is 3-4 gear. when I am on the Ryca it is 2-3 gear. Just something's just not right.
