Bye-Bye Bthou!

Suzuki GSXR 1000 K4 Review - BirotarUK


Have you ever made a connection with a bike? It sounds strange, but anyone who has will relate to this. The attraction of a liter superbike is an incredible thing.

Its torque and power delivery is something that is hard to describe and can be quite frightening, especially if you're coming from a lesser powered machine. 

We bought the GSXR 1000 K4 in August 2015. You can find out more about here.
We've done everything on this bike apart from taking it down a dirt track.

- Commuting
- City Riding
- B-Road blasting
- Track days
- Long distance European journeys
- Short weekend away

One thing we noticed immediately was that it's an extremely capable machine and it is a bike that left you wanting more after every ride. We never got off the bike wishing it was different. Full satisfaction after riding the Bthou, every time. 


The Bthou is now sold to make some room in the garage, so we thought we would put together a list of the bike's features and spec.

- Ohlins rear shock
- HealTech GI with ATRE
- Next-Up QS
- Titanium Yoshimura Tri-Oval 98dB
- Braided lines
- EBC HH Sintered Pads
- Pirelli Diablo Rosso III Tyres (190/55)
- Power Commander III
- R&G Crash Protection
- Tinted Screen

The bike is going to be missed, but times and requirements change! 


The bike overall was very comfortable and very stable at motorway speeds.

We rode the Bthou from London to Turin last year. We did the return journey in one go, 18 hours in the saddle was perfectly bearable with the only problem being fuel range! The bike was brilliant.

Basic maintenance is required on models of this age, naturally, like any other machine. Particularly with the K4, kickstand switches, throttle cables, fuel pump strainers are to be looked at if you're buying a used one!

It's all about ensuring that the bike is not going to let you down, not by trying to predict the impossible but by having a look through your owner's manual and service intervals (or Haynes manual if you have one). These checks will give you a good idea about the items that should and can be replaced affordably and easily, before "the bike lets you down" when instead, it's basic user error that is causing the problem!


One thing that we will say about the GSXR 1000 K4, and any 150-160+ hp bikes. On a track day, you have got to be a seriously experienced and talented rider to be able to use the full bike's power to really stretch its legs and bring it to life.


As we experienced at Bedford Autodrome last year, reaching an indicated 188mph on the back straight is easy. Opening up on a straight line is fine. It's understanding when and how to open the throttle on the exit of a corner, using the tyre just before reaching the limit of grip. 

The reality is though, that it can be ridden gently. It can be ridden slowly, and it's not going to bite you back if you treat it with respect. Arguably, that's the same with any bike. 

So here is a short gallery of that represent our time on the GSXR 1000 K4, formally known as, the Bthou. One of the first bikes we really made a connection with! Thanks for the good time :D

BSB With Pirelli - Saturday 14th October 2017


BSB With Pirelli - Saturday 14th October 2017

Pirelli invited us to the final round of BSB, hosted at Brands Hatch. With an action-packed weekend of racing, and ‘it all to race for’ in the final showdown, we couldn’t say no.

Little did we know Pirelli had a little surprise in store for us…

We’ve always watched BSB from the ‘outer circle’ wondering just what goes on in that packed paddock. Pirelli invited us in for an exclusive 
walk around of areas not usually accessible to the general public.

We expected a quick walk around and maybe the chance to get into a team’s garage, but instead, we’d be rubbing shoulders with Fred Clarke as he delivered live commentary. Finally, great to put a face to that infamous voice of BSB Commentary.

We then watched free practice from the top of the world, a great experience with an incredible soundtrack.


Thinking it couldn’t get any better, we were then taken to the Tyco BMW garage to see how it’s all set up. Certainly a different world from the track day setups we’re used to here at BirotarUK.

With team members changing tyres, checking pressures and K-tec suspension experts dialling in the set up that’s being fine-tuned all weekend for optimum performance. There is certainly a few quid being chucked about these garages on a race weekend!

Knowing we love the technical aspects of things, and since Pirelli are the tyre supplier for BSB, it was time to see the logistics of tyre delivery to BSB riders. With BSB hosting approximately 200 riders across all classes, Pirelli brings 4000 tyres for the weekend, yes four…THOUSAND. This includes a mixture of slicks, Supercorsas, wet and rain.

We managed to catch the tyre fitters at a quiet time but they are usually flat out all weekend.

It was great to see what really goes on in the paddock during a BSB race weekend, especially the Final Round here at Brands Hatch. It’s as chaotic as you’d imagine, but controlled seamlessly (most of the time). An amazing experience that we thoroughly enjoyed, we’re now off to catch race one!


Stay tuned for more updates tomorrow!

BMW R NineT Review

BMW R NineT BirotarUK Review

Since the R NineT was released in 2014 (a time when café racers could be found on every corner and coffee was cool again), we’ve often wondered what it would be like to ride and own. We’re all too familiar with the 1200cc air-cooled flat twin, but not in what looked to be an agile and awesome looking bike.

On an almost sunny Saturday, we had the opportunity to take this R NineT for a ride and see what it was actually like. We’ll start off by saying that it really is a frisky little number. Almost like that first Tequila shot on a night out, you’re never sure if you want it but once you start you never look back! Or, do you...?

Before you’ve put the key in the ignition you’re addressed with classic looking dials coupled with a modern, switchable digital display that shows everything from engine temp to battery voltage. Keys in, dial, sweep, hit the ignition and the bike purrs into life; classic 1200cc boxer sound. The bike we rode had an Akrapovic end can, giving a beautiful sound in classic Akra style.

The R NineT has a comfortable riding position, BMW seems to have got the ergonomics just right for us 5ft something’ers. We're not sure a pillion would be comfortable for too long but the option is there.

Whilst enjoying some fine country rides, you quickly notice that whilst the ergonomics are comfortable, the ride is quite firm, often feeling a large bump pass right through you. The suspension is adjustable though, so we’d mostly likely soften it up a bit for day-to-day use.

With 96hp and 74lb of torque, it’s very easy to make progress on this bike. Most of this torque is delivered low down, making for easy town/city riding. Fourth gear is brilliant, bags of torque encouraging a huge smile as you accelerate out of wide sweeping bends or up the slip road onto the motorway! So what’s it like on the motorway we hear you say...? It’s OK. 70mph is comfortable with no screen, much the same as modern naked bikes without a screen. It wouldn’t be the first choice for a long motorway journey when there’s a R1200GS in the garage.

The R NineT is surprisingly smooth, we’re used to this engine in a thumpy R1200GS but BMW has worked their magic and smoothed things out a bit here. Downshift too abruptly and you’ll still get the obligatory sideways wobble that most 1200cc owners are used to.

As you’re cruising around, you can’t help but think: 'if we made space for this in the garage for this bike, what would the running costs be?'. Well, with BMWs arguably reliable shaft drive and super reliable engine, regular servicing would keep you on the road. Even valve clearances are no more than an hours work on this engine. On the motorway, we saw just under 60mpg but returned an average of 49mpg in the six hours we had the bike…not bad when you’re having fun! 

The R NineT runs sensible tyre sizes, a 180/55 rear means you could even run super sticky Supercorsas if that’s your thing. The bike we rode came with Metzeler Roadtec Z8’s and we didn’t have any complaints.

Handing the keys back and hopping back on the GS left us wondering if there would be space in the garage for one. Reality is, we’d struggle. Not for lack of room, but it just wouldn’t get used unless it was a sunny Sunday afternoon (or maybe a track-day), an expensive ‘coffee run’ bike, even though it looks SO good.

We can understand the appeal though, it looks great, handles well, really moves and sounds amazing, just doesn’t fit our needs…for now anyway.
