I use the application to navigate fun curvy roads on my motorcycle from
preplanned .gpx routes and it works great. The one annoying feature though
that I hope someone can help me with is for every sharp corner it tells me
turn right or left in so many feet when there is no turn it is just a curve
in the road. Is there a way to turn this off as it gets very annoying on
really curvy roads.

In contrary of natively calculated routes,
OSMAnd ( other apps usually too) takes GPX route as a simple point sequence.

The is no difference to an off-road outdoor GPX route, just this time
points happen to sit on roads.

OSMAnd in gpx-route-following mode ignores road network data from the
vector map.
The map just serves as a background.
You could as well use a raster map without any routing data.

OSMAnd has no idea if the GOx route turning is just a curve or a
junction/crossroad.Sonit announces every turn.


The exception is, if the GPX is generated with navigation hints by BRouter
navigation.
GPX will tell OSMand, where and what to tell.


It even does not tell you to turn, if the turning means staying on the
major road( not by traffic to priority, but by road OSM class.)


The easiest way to generate GPX with hints is to use Brouter-web frontend
http://brouter.de/brouter-web with turned on OSMAnd aware hints in the profile
and download the GPX file.

You could also calculate the route natively within OsmAnd and save that to
a GPX.
This how-to video is aimed at routing via hiking trails, but the principle
for roads is the same:

Osmand talks to much, but it talks normaly, if you have to change the
direction.
Brouter hints produce a very silent phone. But it is in my opinion too
often silent, if you have to change the direction.

So the hints produced by osmand are more annoying, but less missleading.

Brouter does not announce every direction change
by design, it tries to omit trivial ones.

This can be modified in the profile.
A quote from my unofficial Glossary GitHub page:

"Priorityclassifier is a BRouter numerical parameter calculated for ways
and used for generation of pictogram/voice navigation instructions. Higher
values means the more significant(=noticeable) way, AFA it can be predicted
from OSM data.

To avoid navigation instruction flood, the BRouter author ( Arndt
Brenschede ) decided the instructions are provided only if:

You are supposed to turn at a crossroad/junction and the other alternatives
have the same or higher priority.

You are supposed to go straight ahead and some of other alternatives have
the higher priority."

I used Priorityclassifier with the value 10 and made still this experience.

It does not make sense to use a single value.
It should be evaluated per way segment basis within the profile script file.
If fact, the more values the better.
