larger rear sprocket on te310r advantages vs. disadvantages

[siens]

Can anyone give advice on changing the rear sprocket to a larger one on a te310r ...any advice would be appreciated. Thanks.

What sort of riding is it for.? On steeper, nasty hills I would go for a 52tooth. The down side is, You will lose top end speed.

50 too tall, 40 too small , 50 renders 1st useless, 47/48 would be ideal, decent cruising 6th and not render 1st useless.

I'll be going 48 next time

What do you currently have installed?

I went 45. Street is pretty good. I think if you do much steep stuff a 47, 48 or 50. Just set down and see what kind of riding you do and where you want to compromise. Fire roads and the occasional steeper section for me and I think a 47 would have been a better choice. But I do have a Rekluse and if you get one the 45 might be ok.

Stop reading and start wrenching....now, or soon, or when you get around to it...
The swap to a larger rear sprocket is an "epiphany" (My take; see "# of links?" post, and many others.) If you plan to use this bike for off road duty, go get a new chain and sprocket (I picked a 48t for our two bikes) ASAP.
Cheers

I run 13/50 and think it's great. If you ride any singletrack at all, you will not find that the 50 "makes first gear useless" at all. In fact, I think in those conditions you will be wishing for 52. However, the 50 is a very good compromise IMO. It makes first gear useful in the tight stuff, and still retains some speed on top. The problem with the 310 is the crazy tight gearbox spacing. Because of that, any final drive ratios are going to be a compromise. You just need to decide where you want to compromise...the top, or the bottom?

Been using the 45 for awhile now, recently at China Hat, woods in Hood River, Imogene Pass in Co.. Simply means more clutch on steep starts and slow descents. It is optimum for use on the street if you need to be there for any amount of time (45-55 mph). The majority of my rides though, I have hauled my bike to the trailhead and I am usually using the first 3 gears. I don't carry a gas can in my van so need to hit the road to fuel up. While a compromise, I now am leaning towards a 48 and another chain. For 98% of my riding it would seem optimum. On the street clearly this will land the bike where it vibrates the most at 45-55 so I will be moving to the shoulder and allowing vehicles to pass. Knobbies and floppy fenders don't make for great street bikes anyway.

Thanks for the feedback..I will post my results when I decide what to go with..thanks.

i run 13/52 on my 310 and its maybe a fraction too short but only in the more open stuff. i tried a 13/49 for a while (had a sprocket lying around) and found it too tall for my riding. i reckon i will go with 51 when im due for a new sprocket.

13/48 for lots of open riding
13/52 for really tight riding

I've got 48 on now and most likely go back to standard 50 soon.

There's something about 13/50 and these bikes...

 

[Johnrg]

OK... decided to stop compromising and have all new 13/50/ plus chain on the way.

If you're in Forked River, stay with stock 40 rear. Wharton Forest is all wide open. I normally ride North Jersey rocks and swapped my 40 with a 50, which is perfect. I can only top out around 50 mph but hey, my street shots are short between trailheads.
When I went down to Wharton I put the original 40 back on and it was perfect for those sandy roads down by you.
Back to the 50 up here.

Absolutely. I got a 50 tooth on my te 310 and all my riding is in Wharton. My riding buddies have a WR 450, a DRZ00 and a KTM 450. We do mostly open road higher gear stuff with an occasional shot on the asphaly. I am thinking about going down to a 48. That and getting rid of the stock Metzler Karoos I am glad they finally wore out. With the 50 tooth it tops out fast. I am thinking I would do better with the 48.

I run a 48 in Wharton Forest sandy roads and tight single track.. bike will still go over 60+ on the street.. but at 55 and above it gets "real nervous"... front end is a bit "twitchy"! ;-)

the standard factory racing set up was 13/50. I ran 52 for a while but it was to low on decel had to use alot of clutch slipping to keep the wheel hop down. PS these are hi reving modern race motors, short stroke, with close ratio gearboxes, this how they were designed.
