Alright guys (and girls)...

Theres a Sprint thats held near me every year, Hoghton Tower if anyone knows it? Been to watch the last few years and it looks pretty fun, wouldnt mind having a go.

Ive had a look on the website and i think i can get away with having a one day ACU licence from the people who organise it, anyone had one of these before?. Im still on my A2 so i dunno if that would make any difference if anyone knows?

As for the bike, ive got the VFR and the H100, both just road bikes, so if i enter them into a road class category i wouldnt have to change anything would i?

Cheers peeps...

Tom

Sprint racing is quite likely a lot laxer on scruiteneering.

Actually; details here: https://www.acu.org.uk/Uploaded/1/Documents/ACU%20Handbook%202017/ACU%20HANDBOOK_2017_lo.pdf

Seems lockwiring and as I read it a chain guard will be needed.

Never seen a requirement fo lock wiring when sprinting. Mostly they want a chain guard and leathers that are either 1 piece or zip together. If you have a road licence you're unlikely to get turned away.

Your best bet is to email or phone the organiser. Most sprinters love nothing better than to talk for hours about it especially if it means attracting new blood.

They made sure the petrol tank was attached to the bike, my wheels were bolted on and that I had some sort of brake system.

I think I needed an ACU gold rated helmet too?

It's great fun.

I was second slowest on the day. Got a 19.56s @64mph. Someone else had a 50cc.

Ah, I was forgetting it's mostly straight-line.
(Feeling it's just a handful that have any kind of corner.)

That being the case, good few years ago a load of us went to Straightliners at Elvington - only pretty basic check over of the bike.
Not sure if that was an ACU sanctioned event or not.

We didn't particularly care about the competition - and I'd say it doesn't offer much over a normal drag racing day for the most part, so wouldn't make an effort to go a specific sprint meeting over a general drag event.

Cheers for the replies people Very Happy I'll have a read up on that link, ta G.

Well its only like down the road from me so its pretty handy to have a go at rather than trekking to a proper strip. Im pretty sure my Helmets got an ACU sticker on it aswell so thats good Thumbs Up

Yeah im not planning on being fastest haha, thats why im tempted to have a go on the H100, good excuse to be slow...

I actually find the concrete etc surfaces better for traction than proper drag strips.

The VFR has a close ratio gearbox, so great for track (with corners) but isn't great compared to other 400s.

Not sure what classes they run, but normally they are based on times - the common time classes are 9.5,10.5,11.5,12.5 etc.
You are looking to be as close to that time as possible without being faster - so if you do 10.49 you're at the back of the 9.5s rather than front of the 10.5s. This takes money out of it a good degree as even for 9.5 you don't need to spend too silly amounts I believe (ie big cc bike lowered at the front a bit, with a bit longer swingarm or whatever I would guess.)

Are you confusing it with bracket racing? If you break out of your bracket you don't get automatically punted up into the next fastest bracket, you just don't get a time - you've 'broken out'.

Done some sprinting when younger, even done it at Hoghton Towers. Its a 1/8 mile sprint up the house driveway. Gets a lot of interesting vintage bikes ridden by old blokes like me. Good fun, plenty of bikes to look at in between the 7 or 8 seconds of action. Can't remember the specific bike requirements but not as demanding as other forms of motorsport.

From what I can see this is how Straightliners runs the slower classes and I believe they are considered 'sprint' as far as bikes go.
(Though they seem to have changed the brackets to x.10 since I did it.)

Sprinting you enter your bike into a bike class, not a time class. The rules are tighter for entry because it caters for a wide range of bikes from vintage to classic but you'll find a class for your bike whatever you ride.

Straightliners is mostly bracket racing, not sprinting. You enter into a particular time bracket regardless of what type of bike (subject to some appropriate rules). The two fastest classes top bike and comp bike are bike classes though and run as elimination rounds IIRC.

Ah, a quick look at Straightliners current rules says that they actually do bump a break-out up into the next fastest bracket. I'm sure that they didn't used to do that automatically, but they used to force a bike that repeatedly broke out to enter into the class above.

I could swear when I did it, I was in a 250 class - but the only results remaining (posted on BCF) seem to suggest brackets.

I thought I'd come 2nd or 3rd in 250 class, mostly due to not many entrants - though 12.83 not too bad for a 250 anyway. (It was a tuned KR1S trackbike.)

I'm not sure I even particularly chose a class - we were just there for a bit of fun.

Did you enter a RWYB event? Normal classes don't apply though they do sometimes run alongside regular events.

One other similarity between sprint and bracket is that the clock starts when you break the beam, not with the light. The light just tells you that it's safe to go. In heads-up drag racing the light starts the clock and the first across the line is the winner, so it's easy for the slower bike to win over the faster one if their reaction time is better.

While we were just going along for the RWYB aspect.
However my results are explicitly presented in the "Class 12.50" results.

This was in 2003, so things may have changed since then Smile.

There is also a Hill climb at Leighton Hall, that's not far away from you.
That seems to attract various types of bikes and shouldn't be much different to the sprint except for a corner or 2.
