If its a road bike, chances are its geared exactly correctly to match power with top speed.
Essentially if you add teeth to the rear wheel sprocket, you will shorten the gearing and the engine will hit top revs in top gear before the bike reaches top speed.
If you add teeth to the engine sprocket, the opposite effect, less torque in Top Gear leaving the bike short on top speed.
with a standard 17t front sprocket and a 42t rear sprocket the standard chain size is a 525 ( x-ring or O-ring) 124 link.
You can change the chain sprockets of most motorcycles to get a higher top speed. Reduce the rear sprocket numerically, and/or increase the front sprocket numerically. A higher profile tire will also increase top speed slightly.
It depends on whether you are talking about the front sprocket (the one at the pedals, called a chainring) or the sprocket at the rear derailleur. The lowest gear at the front is the smallest sprocket/chainring. The lowest gear at the rear is the largest sprocket. So if you combine the smallest sprocket at the front with the largest sprocket in the rear you have the lowest gear available on your bike.
The proper sprocket combination for a Yamaha XTZ 125 depends on the specific gearing requirements of the rider and the intended use of the motorcycle. Generally, a common sprocket combination for the XTZ 125 is a 14-tooth front sprocket and a 48-tooth rear sprocket for a good balance between acceleration and top speed. However, some riders may prefer a different combination to suit their riding style or terrain conditions. It is recommended to consult with a motorcycle mechanic or experienced riders for personalized recommendations.
To change a front sprocket, first ensure the motorcycle is on a stable stand and remove any necessary bodywork for access. Loosen the chain and remove the chain from the sprocket, then use a socket wrench to remove the retaining bolt or nut holding the sprocket in place. Replace the old sprocket with the new one, ensuring it's oriented correctly, and then reassemble by tightening the bolt and reattaching the chain. Finally, adjust the chain tension as needed and check for proper alignment before taking the bike for a test ride.
How do you remove the front sprocket from Honda trx 250r
Under the timing belt sprocket, on the front of the crankshaft.Under the timing belt sprocket, on the front of the crankshaft.
2 up in the back 1 down in the front, will give a better race time, faster acceleration, but take a little off top speed
A bigger front sprocket gives a higher top speed. A bigger rear sprocket gives a lower top speed. A bigger front sprocket is less torque more top speed, and a bigger rear sprocket is more torque less top speed.
Absolutely, depending how messed up it is, it can damage your chain, which can damage your rear sprocket. The chain can jump teeth or jump off and jam the back wheel or engine. If the chain breaks you could be heading for a whole world of physical and financial pain. Get it changed.
The fairing.
YOu need to remove both CV joints. after that the shaft on which the front sprocket rides will come out of the front diff. Just hit it back with a rubber mallet and put your new sprocket in place then hit from the other side to run the shaft through the sprocket. Reassemble. The front 'axle' or diff is held in by the chassis metal being bent around it. it is not removable.
