Rumble Pack doesn't fit on the Tiger's
luggage rack and the J hooks are too thick
to fit either on the rack or under the seat.
Eclipse Rumble Seat Tail Bag
by Rick K. for webBikeWorld.com
Eclipse motorcycle luggage has been made in the
U.S.A. for just about as long as I've been riding
The company was started in 1973, and it was in the
spring of that year, if I recall correctly, that I purchased my first
bike, a 1968 Bultaco Metralla (of all things).
Back in those days, I didn't know a tank bag -- or
Eclipse Luggage -- from a hole in the wall, but
somewhere along the way, as I moved from bike to bike in
the '70's, I became aware of Eclipse through
advertisements found during my cover-to-cover
assimilation of each month's Cycle magazine.
And here we are, just like that, in 2006.
Cycle magazine is long gone, unfortunately, along
with my Metralla, my youth, the war in Viet Nam and,
thankfully, double-knit polyester. But don't
despair, because Eclipse is still with us!
After all this time, I came to the realization that I never did
a piece of Eclipse luggage, and I figured it was about time. I
had been looking for a very small tail bag that would fit on
the luggage rack on our 1998 Triumph Tiger hack bike
anyway, so maybe Eclipse had a solution.
I wanted something much smaller than the Triumph hard
luggage tail bag that came with the bike; something just big enough to hold
maybe a pair of gloves, a sweater, a bottle of water and
Looking around on the Eclipse website, I ended up
ordering their #301 "Rumble Pack" tail bag, or "tail
pack", as they call it, which looked to be about the
smallest tail bag they make.
The Rumble Pack measures
long by 10.5” wide and it's roughly 6” deep by my
measurements (which are slightly smaller than the
measurements listed on the Eclipse website).
That's about 30.5 by 27 by 15 centimeters for you metric
The Rumble Pack expands by unfastening 5
metal snaps around the perimeter and pulling upwards.
This nearly doubles its depth to about
12" (30.5cm). Eclipse claims that when the
bag will hold a full-face helmet when it's expanded, but
since I haven't tried it, I'll have to take them at
Eclipse lists the capacity of the Rumble Pack at 650
cu. in. (11 liters) unexpanded and 1200 cu. in. (20
As it turns out, I should have measured the Tiger's
luggage rack before I ordered a bag, but I was too lazy that night to
trundle down to the garage to take a peek. The
Rumble Pack is too big to fit on the Tiger's rack, plus,
as I have now discovered, it's
really designed to fit on the back of a motorcycle seat
not a luggage rack -- or at least not the Tiger's luggage
The Eclipse Rumble Pack attaches to the bike with
four simple J hooks. The bag has two channels, or tubes, sewn
crossways on the bottom. A bungee cord is looped
through the channels and around the perimeter of the
bottom of the bag and
it has two large vinyl covered J hooks attached to
each side. The J hooks are about 1/4" round (6mm).
The bag is mounted by stretching the hooks down and
catching them underneath the motorcycle's seat or by
hooking them on to the bike's frame or other appropriate
Inside the bag is a clever bungee cord tightening mechanism
that Eclipse calls a "Cordlock". This can be used
to cinch up the bungee cord if necessary to keep the bag
securely fastened to the bike. The Cordlock is
located underneath the hard stiffener panel located
inside on the floor of the bag, and it can be pulled
tight to put tension on the bungee cord if necessary.
The Rumble Pack fits perfectly on the passenger
(pillion) section of the Tiger's stock saddle, but the
J-hooks that are provided on the bag are too thick to
fit under the lower lip of the seat. The seat
bottom is too close to the Tiger's bodywork, and
although I can remove the seat to place the hooks, I'm
afraid the tension will tear the seat cover.
I can squeeze
the hooks under the plastic trim located under the Tiger's
seat, but the tension from the bungee cord is, I think,
too much for the relatively flimsy plastic trim, which
was meant only as a styling accent and has little
I think it would have been better, at least in this
application, if the J hooks were made from flat metal
instead of round bar stock, or at least if Eclipse would
offer the option of flat hooks for those who need them.
Flat hooks would probably slide very easily under the
lower edge of the seat. Unfortunately, the Tiger's
luggage rack is shaped in such a way that the Eclipse
bag will not fit, even though Triumph added a couple of
slots that are specifically designed for use with hooks.
Other than that, the bag works well. The bag
itself is not waterproof, but it does come with a
(claimed) waterproof cover. The cover is a simple
affair, made to fit the bag when expanded. It has
a piece of cord sewn into the bottom with a simple
spring-loaded button to tighten the cover around the
I'm not thrilled with the way this works;
first of all, the cover is sized for an expanded bag, so
it is too big for the bag when the
bag is not expanded, and the cover's simple tightening
mechanism isn't very robust. I'm continually afraid that turbulence at speed will cause the cover will fly off
the bag because I can't seem to get the cover tight
I also wish the bag was at least designed to be water
resistant, at the very least. The design is such
that even the briefest of rainstorms seems to allow the
insides to get wet. I think the problem is that
the zippers are not adequately protected by the
simple flaps that cover them.
The bag's cover opens via two zippers located on each
side of the top cover just under these short flaps, and
there's also a small section of Velcro at the rear of
the cover that holds it in place. A small pocket,
roughly 6" by 5" by 1" deep (15x13x3 centimeters), is
located on top of the cover. This pocket opens
with a zipper and the zipper does not have a protective
The bag has a single cavity inside that's useful for
stuffing all sorts of carry-on items. A mesh pocket is sewn to
the back of the cover and is useful for holding the
Rumble Pack's waterproof cover when it's not being used.
The bag also has a strip of reflective material
around the perimeter, with a reflective Eclipse logo on
If the Rumble Pack will fit your bike, and if you don't
mind that the bag isn't really waterproof unless the
cover is installed, it may work for you. Make sure
that the bag's dimensions will fit your bike, that you
have a suitable location for the J hooks and that the
hooks aren't too thick for your mounting application.
