​I would do even better by avoiding using 'if'​
​ at all:

map $http_user_agent $keepalive_timeout {
    default 75s; # Put here the wanted default value (taken from
keepalive_timeout
<http://nginx.org/en/docs/http/ngx_http_core_module.html#keepalive_timeout>
docs)
    *regex* 0;
    *for* 0;
    *blacklisted* 0;
    *user agents* 0;
}​

keepalive_timeout $keepalive_timeout; # At http, server or location level,
as docs state
