Honda VFR400 NC30 customised by Tina Parkes


Just a quick email to say thanks for the kit for my VFR it fitted great, it took 3 days to fit spray and sticker so she was back on the road in no time.

We went to BSB last weekend there were lots of people taking photos and asking questions where i had got it from and how hard it was, so pointed them in your direction.

Thanks again

Suzuki GSXR customised by Philip

Hi Gavin,
Hopefully the pics of my gsxr have gone through ok. This is what I have fitted the up to now on my bike:
Yoshimura TRC carbon fibre twin pipes,
Y piece de-cat pipe,
Power commander III usb with custom map, Evotek exhaust hangers, R@G bungs, Tinted light cover, EBC HH sintered pads, Double bubble screen, Scottoiler, Rainbow indicator bulbs, R@G tail tidy, Custom brake reservoir cover, Suzuki GSXR tank and yoke covers,

Tyga performance Carbon fibre parts fitted:
Front fender,
Rear hugger,
Heel plates,
Chain guard,
Tank infills,
Tank cover,

The quality and fitment of the carbon fibre parts you have supplied me a of a high quality. They fit perfectly and look great. The same carbon fibre parts from Suzuki uk would of set me back £1293. The tyga carbon fibre looks just as good if not better than the Suzuki parts they offer at a great price. Thanks again for been helpful and allowing me to collect the parts in person. Feel free to include this and the pics of my bike on your website. I have never seen a blue/white gsxr fitted with the carbon tank cover before, it's normally the black bikes that often get shown. I think it goes well with
the blue/white paint scheme.

NSR/MC21 1999 JOEY DUNLOP REPLICA customised by Nigel

Hi Gavin,

I've been looking at your customers bike page & noticed you have no NSR,s on display, (HOW VERRRY DARE YOU)

Anyway I've had lots of parts from you & thought you might like to see what I've made with it all. I think you will be suitably impressed, as are the crowds it pulls down Matlock Bath..I won't go into the spec as there's too much to list but hope you like what you see & put it on your site for others to view.

Many thanks for all your help Gavin.

Honda NC30 customised by Stuart Fitton
Hi Gavin
Not quite finished yet as it now has a misfire!! I also need to mount the expansion bottle and fit the screen and do a bit of tidying up. I'm having some small fairing panel made to go from the tank to the front of the seat pad as on the duke.
Ducati 916 front end complete.
The tail is also 916 fitted to a heavily modded subframe, I lengthened the lower rails and had to weld some mountings to support the seat pads. The undertray is a modded original too and that makes mounting the electrics and tools fairy easy.
I had a bit of trouble with the front fairing and I ended up modifying the headlight bracket. I've looked at one of yours (you can see I have an EX J4P bike in the corner) and it is different. Anyway, I'm happy with the fit.
