Black Shadow Restoration

Vincent Black Shadow

We have recently finished this restoration of a 1951 Vincent Black Shadow.
The bike had been stored in a partially disassembled state for over 30 years and arrived to us in a wheel barrow and several box's.
The bike underwent a complete restoration and was rebuilt to as near original specification using as many of the original parts as possible. However, the bike benefits from many new parts and has some sensible modern updates such as 12 Volt electrics, Alton generator and Omega pistons.
Six months and a lot of work later the bike was delivered back to its very pleased owner.

BEARS Race Series

BMW K100 race bike

Last weekend at Mallory Park was our first outing on the BMW K100 race bike in the BEARS Championship this year.
This was however the 3rd meeting of the championship as we missed the rounds at Anglesey and 3 Sisters.
The first race was on the other bike, the 500 Vincent, this ended after 2 laps when an oil leak reaching the tyre resulted in a high-side. No major damage to bike or rider, but the Vincent was out of action for the rest of the weekend.
The BMW K100 proved to be better than ever after the improvements over the last few months where we gained some hp on the dyno and changed a few other bits. 4 wins from 4 starts, cant beat that!
The best race was had on Saturday afternoon when, after a coming together with a Guzzi on the start, we headed off dead last and then eventually caught and passed the leader with 3 corners to go to the flag.
There is an on board video of one of the races on our YouTube channel here:
Next meeting is Lydden on the 5th/6th July

BMW K100 TT Cafe Racer

BMW K100 TT Cafe Racer

We have finished the latest K100 build and in record time, we started it during a quite period and just kept going at it, result was that in 5 weeks it was done.
This build was not planned, but the donor bike was offered to me at a good price and i couldn't say no..
Initially we thought we would just use it for parts but underneath the battered bodywork there was a very good bike in excellent mechanical order so we decided to give it a new lease of life with the intention of keeping the bike at BSK SpeedWorks to use for trips to the cafe, bike shows and the like.
It is however, for sale, more info on the bike here: BMW K100 TT Cafe Racer

K Series 4 into 1 Exhaust Collector

BMW K Series 4 into 1 Exhaust Collector

If you are building a K100 or K1100 special or want an alternative to the stock silencer, then this new product from BSK SpeedWorks could be just what you have been looking for.
We hadn't found a suitable product for this purpose for our K projects or race bike so we decided to do something about it. The result is a collector that can be fitted straight onto the stock header pipes and allows the fitting of any 2" silencer you like.
We made a prototype, which is now fitted to our racer, and started a small production run, they are available to order now. More details available here:

K1100rs & R100rs rebuild completed


A couple of long term residents at the workshop made the trip back to their owner today. A 1995 K1100RS and an 1982 R100RS, both having undergone some major refurb work and alterations to the customers specification.
Both bikes were in reasonable condition and had low mileage when they arrived but had suffered generally from the passage of time.
After the major work was done it was decided that they would both be finished in BMW Avus blue/Motorsport paintwork. The K11 also had its tierd looking silver drivetrain finished in high temp satin black and the wheels in gloss black. The brakes were completely rebuild, fitted with braided lines, had new discs and the calipers finished in a high temp red.
A RAM shock and front springs were fitted along with some rechromed stanchions as the originals had lost some of their chrome not through wear but rust from standing without use.
We were pleased with end result, as was the customer, and he now has two fantastic examples of these great bikes to enjoy this summer and for years to come.

BSK SpeedWorks BMW K100RR - Built in Britain winner 2013

Our BMW K100RR has taken the top prize in the Carole Nash 'Built in Britain' competition, in the Pro-Builder class!
The competition was run by Carole Nash, Motorcycle News and the guys at Insidebikes.
The announcement was made this week at the Motorcycle Live show at the NEC and the owner, Frank Hunsperger, was presented with a cheque for £1000 by world superbike star Johnny Rea.

BEARS Race Series winners

Ben Kingham BMW K100 2013 BEARS Champion.

We were at Mallory park at the weekend with British Historic Racing for the penultimate round of the Classic Racer Magazine sponsored BEARS Championship with the K100.
An enjoyable meeting where the bike ran faultlessly again resulting in four wins, making 10 from the last 12 starts.
With one round still to go at Cadwell Park on the 28/29th Sept, we are more than 60 points clear at the top of the table so it looks like the Championship is ours.
We will be at Cadwell Park for the last round and we hope to have the K100RR road bike and its owner there along with K100 racer, the finished Egli Vincent(hopefully!) a Vincent grey flash and the Vincent HRD racer, should be a good do!
Lastly, please take a moment to vote for the K100RR in MCN's Built in Britain competition, which the new owner has entered. The bike is in to the last 60 and we need some more votes to get it into the top 12.

Four wins from four starts was the result from last weekends Classic Racer BEARS championship round held at Darley Moor.
The K100 was going very well despite this being its first time out since last season and with some untested new parts fitted.
We will miss out the next meeting at 3 Sisters, but look forward to the following BEARS race at Lydden Hill on the 27/28th July.

BMW K100 racer

We will be entering our BMW K100 in the BEARS Championship meeting the weekend after next (18/19th May) at Darley Moor race circuit.
This will be the first race of the season and we are hoping that some of the modifications we have made to the bike over the last few months will be an improvment over last years setup. We are still running the same motor for this meeting but hope to have the new improved and higher tuned engine ready for later in the year.

K100 Race Replica build - Finished

K100 Race Replica

Our BMW K100rs 'BEARS' road legal replica is now finished.
The build took just 2 months to complete and features many parts as fitted to the race bike including the rearsets. For these, copies from the racer were made and we now have a batch of parts to make more which are available to purchase.
Unlike the racer there are some minimal road nicities fitted like a side stand and lights but we wanted to keep it more BMW racer than BMW tourer so any unnecessary parts are gone. In fact nearly 50kg of them!
The rear RAM shock still needs to be changed from the one pictured to the longer version as fitted to the racer to increase the ride height a bit. After that we just need to get it MOT'd and give it a good shake down/ road test. Cant wait to try her out!
Once we get her out into the daylight we will get some decent pictures taken and offer her for sale.
More about the bike here: You can also see more pictures and info on this build and other stuff on our facebook page:

K100 Race Replica build - Update

K100 Race Replica build

The Road legal, K100 race replica build is in the final stages now, the bodywork is away being painted and the finishing touches are being added.
Need to sort out the rearsets, headlights and the other road legal bits but other than that we are nearly there.
I’m pleased with the way it is turning out and it really does look the business!
We are on target for the bike to be finished by the end of the month at which point, after testing, it will be up for sale. So if you are looking for something totally unique and different, get in touch.
You can see more pictures and info on the build on our facebook page:

K100 Race Replica build

K100 Race Replica build

Here's a shot of the current state of the K100 race replica we are working on, its a 1984 K100RS and will be a road legal version of our BEARS race bike.
The motor/drive-train has been assessed and overhauled and will remain in fairly standard tune for reliability, with a few choice mods here and there.
The bike will benefit from a tuned exhaust and intake system, and huge weight saving over the standard machine, even in road trim we expect in the region of 50kg!
The frame has been modified to a similar spec to that of the racer, chopped and strengthened at the rear and then powder-coated blue.
An adjustable RAM gas shock will be used on the rear and the front end will have an upgrade over the racer, with later forks and brakes as this one wont have to conform to the BEARS 'pre 1985' race rules.
The bike should be finished early in the new year and will then be up for sale.
More pics and info will be added along the way, you can see more on our facebook page:

Second Hand Alley!

Second Hand Alley

We have a new page on the website where we will be listing any used parts we have for sale.
I have just added loads of early K100rs parts that were removed from our donor bikes as not required, things like seats, fairings, lights, wheels and lots more, these are all reasonably priced so grab them while you can, it might be worth keeping a spare or 2!
Take a look: Second Hand Alley
We will be adding more parts regularly, for BMW K series and other makes, so check back soon.

RAM Shocks now available!

RAM Rear Shocks for K Series BMW

RAM high performance shocks, specificaly designed for the K Series BMW are now available from our webshop.
"Here is the latest development from Realm Engineering Ltd. who have been manufacturing speciality Replica Sports cars for the past 35 years – the Café-Moto range of Motorcycle products, starting off with a range of RAM Alloy bodied and CNC machined shock absorbers. So how, may you ask, are Realm involved with motorcycles? The company principals have had a lifelong passion for bikes and a lifetime of design and development in the field of road going and competition cars. It was this side of the business that brought them into direct contact over the past 35 years with competition shock absorber designers and manufacturers.

Applying their accumulated knowledge of building and racing cars and the purchasing power of a large speciality car manufacturer, they were able to have the shocks developed and manufactured at a very competitive price. The unit was based on the same Alloy CNC machined externally adjustable unit they are using on their Cobra and Jaguar replicas. After exhaustive testing by the manufacturer, and over 10,000 miles of road testing – they were convinced that they had a product that would stand scrutiny with the best currently available shocks.

The first of these have been designed specifically for the BMW K75 / K100 and K1100 models and there are also shorter bodied versions available. Yamaha TR1 / XV750 / 920 also available.


RAM “Classic Twinshock” range:
Following on from 3 years of successful Monoshock sales, Realm are now marketing a range of twinshock units suitable for Café Racers and Specials. Based on the same successful formula as the Mono range, the new Classic shox have been developed specially to suit the requirements of the Café Racer / Special builder.

Initially available in a variety of lengths suitable for popular Café Racer donor bikes [ Honda, Yamaha, Moto Guzzi, Kawasaki, Suzuki, Triumph and Norton ] these lightweight and sophisticated shox are set to become the industry standard for quality and value."
