Moto Martin post classic race bike

Hi all

I must say i'm very impressed with the quality and workmanship. That's gone into the ongoing projects I've seen.
So i thought i'd add my pathetic attempts at building a bike form scratch....

So there i was a few months later getting bored with no bike to play around with. So i had a look at what bits i had lying around and thought. I know lets build another bike. I have most of the bits. I just need a frame.....Yeah right.

So the search began for a suitable frame from the era. P&M's and XR69's are like rocking horse do do and now totally out of most peoples (including mine) price bracket. I really wanted an F1 frame but thought a magnum would be okay. After looking for months for a z frame. All the ones i'd seen were for suzukis. This Martin frame popped up on fleabay. You may remember it. I knew nothing about them so did a bit of digging and then bought it at what seemed a fair price.

When it arrived it looked ok at 1st glance. The swingarm was bent and there had been a repair done near the rear shock mount.

It wasn't until i tried to fit some crankcases that i realised sommat weren't right. None of the engine mounting points would line up without considerable force. So i could slide the studded bars i made through the holes. As the old original swingarm was bent i had to fit one we had lying around off an old Team Glam P&M (which also turned out to be bent). Made all the spacers for swingarm and rear wheel and fitted it all.

Then i stood back and marvelled at my handy work. I then realised the frame was totally pissed. As the headstock and rear wheel were about 2 inches out of alignment. Bugger

So i called the seller and told him the problem. He seemed to take it well and agreed to give me some cash back on the basis that i got it repaired. Which he later denied agreeing to after i had the work carried out. In hindsight i should have asked for a refund.

I decided i needed raise some more funds and have a drink

I took the frame to ABBA (not the pop group). Where he told me what i already knew. It was bent £75 please kerching. He said he could straighten it for a fee. Which worked out more than i paid for the frame. So i said ta da.

So i took a trip to Motoliner in Kent. Glad i did. He is a top bloke. And straightened the frame for half the original quote. He did say it was a total bar steward and had to get his dad who taught him to help. As it was the worst one he'd ever done.

Good luck with the Moto martin chassis,
did it come from the Northampton area?
As there was one for sale recently but I never got chance to go and see it.

I bet your gutted to have parted with the P+M i still regret selling the one I had many moons ago!
Especially as you say the price's are staggering now. I had to give mine away for £2300 back in about 1990 its one of only two bikes I regret selling. It went to a Forgotten era racer over birmingham way who had a shed full of stuff. No 57 it was.

Be good to see some pics and what your planning, is it going to be a racer or roadbike?

Hi

Yes it was like chopping off an arm. As i'd spent a lot of time making it go and go round corners. Thats about the same as what i paid for mine minus an engine. I think i might know who has that chassis now.

pictures now added to my original post

It would be interesting to know who has it and if its still being raced it was a monoshock one.

These are the only pics I have of it,

Good to hear Ray at Motoliner sorted the frame for you.Top bloke and one who I always recommend to anyone starting a ground up rebuild without any history of the bike.
Regards
Steve

Where was i.....back at the ranch I started to look at the frame again. Seeds of doubt started to creep in. I could see potential weekspots. Mainly the lack of tubing around certain areas. Like the front 2 engine downtubes.The rear shock mount. And from the frame spars back there is very little bracing in the middle. I know the engine is a stressed member. I just hope old georgous George had done his sums. As i'd read somewhere that the H 0nda versions had to go back to full cradle because the cranks were breaking. Good job the z motor is built like a brick shit house.
On the other ramp next to mine was another P&M made for Ron Haslams HRC. If you start to draw comparisons like i did. You can tell the Martin is a road based design. Not a race bred chassis. Although the bronze alloy welding is good some of the work is not.

I think it looks better with twin shocks anyway, does it need the top mounts box sectioning for extra strength or have you used thick plate?

Hi

It's thick plate welded on both sides. Should be man enough....I hope. Not the prettiest job in the world. Can't be seen when the seat is on. :shock:

I had a Moto Martin frame a couple of years back that had also been repaired around the shock mount, obviously a weak spot.:shock:

Worth knowing about for anyone planning to buy one. :roll:

This thread is great reading, I'm ready for the next instalment. :mmm
