Gear Calc can be downloaded from http://www.ironjungle.com/ It really is a
neat program.

Subject: RE: (dr) (DR350) Gearing Change
I'll probably start with a counter change first and see what kind of change
I get since that would definately be the easiest route.
As I've conveyed, my biggest gripe is "my" inability to loft the front tire
easily to clear small objects, holes, small logs or just for the fun of it.
I imagine that the shortened gearing would give the bike a much needed
boost in this arena. It would be nice to just just grab a handful of
throttle, as opposed to coaxing the wheel into the air by bouncing the
front suspension followed by big arm tug, to loft it up...maybe it's just
me?
I'm not to worried about highway use since, IMO, highway use is marginal at
best for the DR350 in stock form anyway. Generally, if I'm riding on the
street, it's just to putter over to a gas station, run a quick errand, or
check out the local sites. The times I've taken it out onto the roads and
rambled along at 60mph I was bummed with the lack of ability to pass cars
trundling along at 55mph without a good deal of pre-planning.
I debated heavily the option of major suspension mods and a big bore kit,
but, won't go this route since the monies spent on those modifications
would be better spent on a different or more capable motorcycle. Further,
I'm a major spode when it comes to offroad riding (which I really enjoy
these days) and probably wouldn't benefit much from the upgrades.
I'm rambling...thanks for the suggestions

Eric and Jesse,
My 98 SE came with 43/15, and I just changed it to 43/14. It gave me a
noticeable increase in torque, but perhaps not as much as you want. I
also have a 13 which I will be trying soon. The good part of doing it
this way is, at least with the 14, I didn't have to change the chain,

Eric,
I don't remember which DR you have, but with my SE and 250 pounds
riding weight, I think you would need to go to the 13 tooth countershaft
sprocket to do this:

At 60 with the stock 43/15 you could go all the way down to third gear
for passing. However, fourth would be well on the torque curve, and
since you wouldn't need two extra shifts (one down and one up) it may be
even better. With the 43/13 60 mph would be around 6200 rpm, way up on
the torque. Fourth would be as far as you would want to shift down to,
and that would be at around 8400 rpm and wouldn't gain you anything. 5th
would be about 7000 rpm and the torque is already falling off, so you
may not gain anything there either.
You said "maybe it's just me", and I think it is, that you may be
expecting too much from a 350. Personally I don't have any trouble
passing at 60 with the 43/14, and not too much difficulty at 43/15. You
should be already "planning ahead" when you ride, and doing so makes
passing much easier. "Pre-planning", as you call it, IS necessary when
riding a bike of this size. If I think I'm going to be in those
situations, I take my BMW R100GSPD and leave it in fifth to pass at 60
;o)>.

Subject: RE: (dr) (DR350) Gearing Change
Wayne,
I've got a '99 DR350SE and I don't think I'm expecting much from it at all.
The bike is relegated to trail duty and road use is very limited. At the
risk of sounding like a broken record... Highway use is not my intention.
I "rarely" ride the bike on roads posted > 55mph. For "me" the DR350 is
just not a fun bike to ride on those roadways. However, it is a gas to
take into the woods or down a fireroad and I do that as much as possible.
Don't read to much into the "pre-planning" statement I made, I've been
riding for the last 20 years most of it on the road and usually around
8-10k miles (not on the DR) a year...not much in some books, a boat load in
others, and in Illinois it's huge...add that mileage into my box mileage
and I come close to 45k miles per year of road driving and I'm pretty
confident in my "good driver" ability.
To clarify what "I" meant about pre-planning, even dropping down into 3rd
or 4th gear to allow for increased acceleration, at 60mph very little is
left in the bike. My '82 Volvo 240 could out accelerate the DR350 at this
speed...and that car is a slug. When passing another vehicle I prefer the
ability to get around it as quickly as is possible allowing me the ability
to get out of the way of any potential oncoming traffic. My VTR does this
quite well, my 911sc does this quite well and my Dodge Caravan does it
marginally well. The DR350 and the Volvo are poor examples of vehicles
with passing power :). This problem is further exacerbated when you are
forced to follow some monkey putting along at 45mph in a 55mph zone while
waiting for a "clear" passing zone to appear.
When I said "maybe it is just me" I was referring to my inability to grab a
handful of throttle and experience a nice wheel stand....and I'll be the
first to claim spode status when riding in the dirt.

Subject: Re: (dr) (DR350) Gearing Change
Hey Eric- you sound like me! (major spode off road, can't and don't want to
hack it on road with the dr350, can't pull wheelies)
I have the exact same bike- '99 dr350se, I actually took the bone stock bike
on a 96 mile enduro course in tight, tight southern NJ woods. I must have
crashed a hundred times. First two modifications were to strip off the
passenger pegs, fender extender, chain guard, side reflectors; and change the
rear sprocket to 47 teeth which required a new chain because I didn't want
two master links in a lengthened one. Rode the same course again (bypassing
some of the more tricky sections this time) and only crashed about fifty
times. Next modification was new Dunlop D756 font and back. Not DOT and damn
scary to ride on the street at any speed, but absolutely awesome off road. I
haven't ridden any trails yet, but I did take it to my local track and it was
very confidence inspiring.
Only problem is that I still can't get the front wheel to loft in any way.
Nada, zilch. Lengthening the chain made my bike longer so I guess I am not
helping the situation.
Besides not being able to wheelie the bike, these mods have made it a much,
much better off road machine.

You can always use the 'express lane' to pass (aka the shoulder), at

Subject: RE: (dr) (DR350) Gearing Change
I had the no wheelie syndrome as well. I changed gearing to 14/44 and cut
the top out of the airbox, problem fixed. I weigh 205 and about 220 with
all the gear. I to have a 99 DR350 but it is the dirt only model. My buddy
bought a 00' XR400 last week and my bike held right with his and I thought
the throttle response on my DR was much better than the XR. I'm also a fan
of the 6 speed tranny. The XR does beat the DR suspension wise though.
Since riding his I plan on getting a hold of Jesse here in the near future
for stiffer springs front and rear (how much am I looking at here Jesse?)
