What size sprockets

[andrewj1680]

What size sprockets are people using? My dt i use mostly seems to stop pulling at 70mph but gets there fast abit too fast for my liking so thinking of changing sprockets i see a few of you suggesting yours do 80mph what size sprockets you running?

[finnerz89]

Acceleration > top end in my opinion.
I'm running 1 tooth smaller on the front. You have to get out of 1st sharpish, but it pulls nicely through all the gears.

[andrewj1680]

I have 1 bike running 15 front and 57 teeth rear tops out at 70mph , another running 16 front 53 rear tops out at 68 another running 17 front 52 rear not sure what its topping out as the speedo isnt working and another 50 rear and 13 up front but no speedo at all lol

[finnerz89]

Looks like you have more experience than most with different ratios lol.

16/57 gets to 70 like wiz head on the run dont take much more than a few seconds to get 80

• if the winds behind you or its down hit

[terry.tz]

standard pipe no mods and sh!t compression i think

[andrewj1680]

@terry-tz think I'll try that 1 combo closest to that i have is 15/57 but it is fast til 70 but wont go even a mph over weather down hill or up hill it doesnt matter, the engine has a tuned cylinder and modded head so even in top gear it pulls like a train but once it hits that 70 thats it

[terry.tz]

@andrewj1680 tbh I'm 80 mph every where I go but with knobbly tyres it feels f!cked up when you're leaning nothing but curvy roads around

[Darty]

I can push 90 now

[terry.tz]

@darty sprockets

[Darty]

13/55T on 520 pitch.

But having tuned it, it still pulls hard at 12k

[terry.tz]

@darty you have a 200 in yours to don't you

[Darty]

@terry-tz I wish, I run a 134cc with racing head work.

[andrewj1680]

I have a rebuilt wr200 going into mine that did 104mph before it was rebuilt and mick abbey tuning cylinder and modded head, I'm having frame painted monday/tuesday i had the wr200 fork clamps bored to take the dt head stem and all the alloy rear swingarm and shock has been stripped right back and polished, not sure if I'm gonna run a wr200 loom and cdi or dt loom with zeeltronic

@finnerz89 IF you have a bigger bike, then I totally agree. But for me the bike was my sole transport and I needed to do dual carrigeway speeds, so I was able to rag it to 80, but sit at 70 comfortably.

[terry.tz]

@darty my bad
@Calum I need to do some carriageway but can't imagine it being a comfortable bike for it il soon find out I guess

[Jens Eskildsen]

14-48 in 520, seems good for most things.

[Calum]

@terry-tz Nope. Horrible. just feels like you're going to seize the engine lol.

[declan]

@calum I haven't been able to top mine out anywhere how do you lads find the space?

[andrewj1680]

@declan not alot of space needed bud they get there nice and fast
