Bultaco Frontera

One of these has become available locally recently, and I can't stop going to look at the advert. I should be looking for a KTM or nice sensible DRZ, but love the idea of an old school enduro / dirt bike. Anyone have experience of these and would like to tell me why it would be a thoroughly bad idea to pick this up, as I know nothing about them?

Bultaco

My best friend had one in the late 1970's. We went riding together in the trails a few times. This bike was awesome but a little bit tempermental.
My friend could do power wheelies in more than 2 gears.

Hot bike...!!!
remember when I was a kid a guy with this big old red Bultaco running around
in the dirt ...we had only 50 cc's crossers beginning of the 80's...memories
It was old looking already and sounded really deep and low for a 2 stroke....
Didn't appreciate it back then as would now
..I'd buy one for sure ina heartbeat if the price was right

Just found the ad. Titled, registered and running. I'd do it if I were you. My friend has a Bultaco street bike and it's friggin' awesome.

Do it! I've been drooling over that exact model for over 30 years.

A Frontera is a gas guzzling bad ass motorcycle. My brother has a 1975 360cc Frontera and its very anti-socially loud for the street and not AHRMA legal according to Dick Mann. Be prepaired to run out of fuel often. A 250cc Frontera is a better all around bike in my opinion. A better option for the street is a pre 1974 (AHRMA legal) 250cc Matador.

When I was a young man (about the time the Frontera was new) all the local Australian Dirt Bike Magazines were absolutley in love with it. I have never ridden one, but I get the impression it was the first "modern" enduro bike ... light, powerful, long travel suspension for its time. It was I suspect eventually suplanted by the early KTM's which were more of everything, and the japanese ... IT400, PE250.

Still I sometimes think that the Frontera is a sort of undiscovered classic. If you get it I might be able to find one of those early magazine tests!

Come on, don't talk him out of it. I rode a slightly earlier model Matador it was very reliable and solid, tough bike. When the Frontera's came out I was hooked but sadly unable to buy one. The Matador was street legal, well for a while until my brother and I broke all the lights. That bike was comfortable running at 65 on the road, unlike other two stroke bikes I have ridden the Bultaco motor just kinda "tuned in" at road speeds, you didn't feel like you were winding it out, it felt like it liked it

On your brother's bike, is it running the ISDT kit, maybe he could rejet for better mpg's??????? Big two strokes are definitely thirsty though.

Well I donít think itís a jetting problem the bike is stock more likely itís a big bore two stroke thing. Maybe we need to keep the Matador thing a secret the bikes are underrated by most and from what I have gathered the 5 speed bikes are very close in specification to a Metralla.

I mentioned the ISDT kit because it's something I wanted to do but never got a chance......the kit for my Matador as stated in the owners manual (graph included), nearly doubled HP numbers IIRC. I'm guessing the kit didn't do anything good to mpg numbers. Mine had decent power (no wheelies) it would have been quite the ride with twice as much. My manual also spelled out mixture ratios for premix including values for running regular motor oil instead of 2-stroke oil.

TACO Frontera

I bought a 370 new back then. I really liked the bike but it was the most undependable scoot I ever had. I traded it in for a Yamaha XS 750 D2. The second year for the triples. It was a GREAT bike! For the dirt I went with a Honda 4 stroke. I've not had a 2 smoke since.

i had a model 152 250 frontera, loved it. - traded it for a model 134. the only weak point is the points ignition. swap in a motoplat and you're ready to rock. the frontera is similar to pursang, aside from: porting, head, and has the larger primary chain weight. oh and center stand, tank/bodywork and lights. i'm sure the big bore frontera's are very luggable, and scream on the top. all parts are available at prices similar to modern bikes components.

RE: Frontera

"...Is that a Triumph/BSA tank? It looks good on the Bul..."

Yes,it is,nsu. I found it on ebay for him,he liked it,so I used it. (When he purchased the Bul,it was wearing,of all things, a Penton Wassel alloy tank and 'way too small Brit alloy fenders-not a pretty picture).
